I welcome those today, I’ll tell you how to

00:00:06

calculate y on an elastic base in the

00:00:09

scad office program,

00:00:11

let’s say we have some, it’s

00:00:14

12 by 8 meters in size,

00:00:18

it’s located on the ground like a dash, the sticks

00:00:20

of which are presented below in the table, how do we

00:00:24

calculate it, we

00:00:26

actually open the ramp, create a file,

00:00:38

set up the units of measurement of the norm

00:00:40

design, I have everything set up

00:00:42

against the diagram and 5 Oksana tenderness

00:00:46

one

00:00:47

I save

00:00:49

the coma

00:00:55

and create a design diagram to begin with,

00:00:59

but there are several different ways of how

00:01:02

the remote control can be drawn, I’ll probably

00:01:03

do it right away with the axes so that I have everything,

00:01:06

we’ll create a rectangular grid of axes in the

00:01:10

longitudinal direction,

00:01:13

we have 12 meters transverse 8

00:01:17

level mark 02 we won’t have any others and

00:01:24

veloster crucian carp

00:01:28

and arrange the

00:01:30

dimensions were

00:01:32

13 by 8

00:01:34

we’ll generate nodes

00:01:37

to intercept this line

00:01:47

and let’s say we’ll draw I’ll come for this we’ll

00:01:50

go to the diagram tab

00:01:54

and here there’s a button to generate a

00:01:56

grid of arbitrary shapes and on the plane you

00:02:00

first need to select a contour

00:02:07

when we have selected the last point twice

00:02:09

on the screen, click twice on the screen and select the outline,

00:02:13

select generation of a triangular mesh,

00:02:16

there are also many ways, we will create an

00:02:19

orthogonal mesh with a minimum number of

00:02:21

elements,

00:02:23

better with a maximum element size, a

00:02:25

triangulation step of 1 meter,

00:02:29

go with three nodes and four

00:02:31

node elements and immediately set the rigidity

00:02:33

of the plates will be concrete plates

00:02:36

up to 25 thickness of 40 centimeters

00:02:43

like this

00:02:45

ok

00:02:47

step plate with a step of 1 meter the triangulation has been created for

00:02:50

me, I’ll install the

00:02:53

whole thing in place in the diagram

00:02:55

here the installation is done on mine

00:02:59

once again we exit the mode now you can

00:03:02

see how it is ours looks like this in

00:03:05

volume,

00:03:08

everything is fine, that is, we have a given

00:03:10

geometry of

00:03:12

stiffness, we immediately also set it, we need to

00:03:15

set boundary conditions and apply

00:03:18

loads,

00:03:21

only we will calculate on an elastic

00:03:23

foundation, let’s actually take some of the

00:03:25

initial coefficients of the elastic foundation

00:03:27

and we will go to the

00:03:29

assignment tab and enter some values

00:03:32

but

00:03:34

hundreds of tons per cubic meter is enough to

00:03:38

invert the selection of elements to repeat that

00:03:41

we have rigidity along the vertical axis

00:03:44

z, we also need to fix the movement

00:03:47

in x and y of coal for let's just add connections

00:03:49

along X and Kubrick

00:03:54

feast the choice of chapters okay now we have

00:04:00

but look

00:04:04

all the nodes are fixed in x and y y and the

00:04:10

wall is

00:04:13

set to the bed 1,

00:04:17

let's also add

00:04:19

loads, it is

00:04:23

necessary for them to have the own weight of the slab,

00:04:27

like the whole inclusion, let us have 11

00:04:30

to 20, let's

00:04:33

save this as the own weight

00:04:39

of concrete and reinforced concrete stone and

00:04:41

wood which we write down there

00:04:46

and the second load we will have a different

00:04:49

load, that is, well, actually the weight of

00:04:51

the building or some other structures

00:04:54

that we just need to learn the main mechanism,

00:04:56

therefore, by setting as a

00:04:58

distributed load on the slab,

00:05:00

let’s say this per square meter, let’s

00:05:04

take the coefficient, let’s say the building is on

00:05:08

top also horses of iron

00:05:10

there will be a load per meter and with a coefficient of

00:05:15

1 and 1 there will be 5 5

00:05:19

onomi

00:05:21

the body

00:05:23

we invert the choice of elements we assign

00:05:27

to see what we have assigned for

00:05:29

each plate

00:05:31

and a half per square meter eye

00:05:33

the load is located we save

00:05:40

I know the combat load as a

00:05:42

constant the same the best thing

00:05:45

to describe is how new

00:05:48

the loads of the given geometry and at the same time the

00:05:50

stiffness are set, in principle, you can

00:05:51

start the calculation, let's check for

00:05:55

errors, no, you are

00:05:58

and we are ready to perform the calculation,

00:05:59

saved, let's

00:06:02

set a combination of load cases,

00:06:05

we will have everything every day, one

00:06:07

combination

00:06:10

more probably for us, nothing special by us

00:06:12

and

00:06:13

version

00:06:16

We perform a linear calculation,

00:06:33

look at the warning errors, for some reason

00:06:36

the diagram has been geometrically changed

00:06:38

to

00:06:39

if we have set everything, it should not be

00:06:42

empirically changeable, then the error will

00:06:44

most likely go

00:06:46

once we check, we will

00:06:52

move indoors, we take this

00:06:56

combination

00:06:58

not in x and in y, we will have zeros

00:07:00

because that our circuit is fixed by

00:07:02

connections in each

00:07:04

positano node, we move with this by

00:07:07

13 2 millimeters, how much the bed coefficient is the same everywhere

00:07:10

across the entire slab now,

00:07:12

and that’s why we don’t

00:07:14

move the same distance

00:07:16

when mine for each breast, we’ll pick us up,

00:07:20

because the difference is the value

00:07:25

in principle everything seems to be fine, it doesn’t

00:07:28

affect us in any way, we will continue to manage it, in

00:07:31

this case we won’t, but if you

00:07:33

encounter something like this, never ignore this

00:07:38

in order for us to choose a

00:07:40

bed coefficient, but we need to do at least

00:07:42

two or three operations, but in our center bed

00:07:46

they will be different from each other

00:07:47

only

00:07:49

slightly less than a percentage there

00:07:52

is what needs to be done open the assignment

00:07:56

after we have completed the calculation

00:07:58

st the calculation is already

00:08:00

1 1 approximate when my

00:08:02

coefficient on the style was set

00:08:04

in advance now we consider the first

00:08:06

iteration

00:08:08

with the real coefficients initially

00:08:12

calculation of the coefficients of the elastic base

00:08:13

click

00:08:15

after we select this

00:08:17

and you,

00:08:19

with the one

00:08:21

that we need to assign coefficients,

00:08:23

confirm with ask from which

00:08:26

load case we will calculate, select

00:08:28

our combination calculation for

00:08:30

and

00:08:32

since we don’t have any site yet,

00:08:34

click continue without the site

00:08:38

again asks we don’t have a site

00:08:42

according to the year, automatically build in When crossing

00:08:45

our slab, the

00:08:48

first thing you should do is always remember to

00:08:51

assign a load to the slab, that is,

00:08:54

click on the means load and click on the slab

00:08:56

just to apply it, if you

00:08:58

don’t do this, it will be an error to count

00:09:00

nothing will happen, so

00:09:02

we have applied the load,

00:09:04

now we will create time like wells, so that

00:09:09

everything will be there at once beautifully, I’ll assign the parameters of

00:09:11

the grid and

00:09:14

place a well somewhere near the center, we only need

00:09:16

one training example, but

00:09:18

in practice you will usually

00:09:20

encounter quite a lot of spam

00:09:24

there, go into the parameters and

00:09:26

create our own soil and remember the wasps

00:09:30

of it, table

00:09:33

1

00:09:35

cop will be shocked small 2 large juice

00:09:38

which from the minus 2 and a half mark

00:09:39

will also be saturated with water, then the third

00:09:43

element is light loam and the last

00:09:46

super sandy layer thickness 09 of us

00:09:49

half 172 has, accordingly,

00:09:51

all the characteristics

00:09:55

and

00:09:57

add 4

00:10:01

layers

00:10:02

and fill them

00:10:39

after you fill the

00:10:41

deformation modulus

00:10:42

elasticity modulus The Poisson's ratio is calculated automatically,

00:10:45

you can look at it

00:10:47

if you,

00:10:49

but if it is not given to you by geological

00:10:52

surveys, then you can open the orbit 5.10 with p 22

00:10:56

and

00:10:58

approximately assign it according to the table,

00:11:02

pay attention to the note,

00:11:05

we will set the Poisson's ratio in front of

00:11:08

me. picked up, let's

00:11:10

take

00:11:21

further what is the coefficient of overpayments

00:11:23

nene and and waterlogging pressure

00:11:25

click on information about us opens information

00:11:27

on the parameters of wells here everything is very

00:11:29

accessible and understandable

00:11:32

zone how to

00:11:35

take into account water-saturated soils the

00:11:37

weighing actions of water

00:11:39

peak later and it is written that in the

00:11:42

absence of data the coefficient of overpayments

00:11:45

nene I understand the unit o Perry

00:11:47

compaction pressure 5 for clayey soils two and a

00:11:50

half for sandy loam and Knightley sands

00:11:53

how do we proceed

00:11:55

from the coefficient we set one

00:11:57

Perry compaction pressure us 3

00:12:00

it’s like

00:12:02

these clayey soils are a crust and two and a

00:12:05

half

00:12:06

it can be changed let’s change it

00:12:10

let us have a list of

00:12:14

this sand .

00:12:18

sandy loam pellegrino so and to be honest, then

00:12:25

we need to

00:12:28

create an

00:12:31

oral geological section ascii

00:12:33

wells

00:12:37

and so he said, well, it’s clear that the

00:12:42

upper limit mark should be indicated right there,

00:12:44

in principle,

00:12:47

we don’t have them, then we

00:12:50

will consider absolute marks relative, so

00:12:51

our upper limit will be zero, all the

00:12:53

rest will be located down, that is,

00:12:56

the value must be indicated with a minus; the

00:13:00

thickness of the first layer is 9 meters, that

00:13:02

is, the mark of the upper boundary of the 2nd layer

00:13:04

will be 09 meters,

00:13:06

so we add the next ones with a thickness of

00:13:08

1 2 layers, that is, two and a half plus

00:13:11

we will have three four money and so on

00:13:17

under

00:13:20

We have the

00:13:22

second soil from the 2 and a half mark, it is

00:13:25

water saturated,

00:13:27

if you go to the help again, here it is

00:13:30

indicated as indicated, read the

00:13:32

help, a useful thing,

00:13:35

so I drew it, I try, from the 2

00:13:38

and a half mark,

00:13:39

it will be saturated with water, that is, we

00:13:42

indicate this overflow pressure

00:13:45

[ music]

00:13:46

with the

00:13:48

third layer

00:13:52

you have

00:13:54

given me all the parameters, you can see what

00:13:56

ours and the soil base look like,

00:14:12

why

00:14:15

open the window

00:14:19

because we didn’t set the boundaries, it’s clear once again

00:14:21

we set 0 minus 9 plus

00:14:28

34

00:14:30

claus

00:14:32

apply

00:14:35

useful look

00:14:39

good

00:14:44

after that

00:14:46

we press the button to perform the calculation

00:14:53

we get the value of the bed coefficients

00:14:58

will be enough for ten values,

00:15:01

our minimum bed coefficient,

00:15:06

well, the

00:15:07

center will have to

00:15:10

take from 700 80 to 900 10 years of hell and the

00:15:14

largest at the edges 1900 you two

00:15:16

thousand tons per cubic meter,

00:15:19

in principle, quite accurately the first

00:15:21

operation was considered to

00:15:23

save

00:15:26

you the next save button data

00:15:27

for the slope after this cross you can close

00:15:31

one the values will appear lair window

00:15:35

asking how to assign coefficients

00:15:37

calculated in the cross

00:15:39

assigned

00:15:42

ten cents the very equipment that we

00:15:45

just saw is the average value

00:15:49

and

00:15:51

now if you look

00:15:57

not at the stiffness

00:15:59

but

00:16:04

you can see now we have a

00:16:05

bed coefficient of

00:16:08

3 sets

00:16:12

our compressible soil thickness is

00:16:14

all accounted for, after that we need to

00:16:16

save everything and read it again,

00:16:23

and

00:16:36

if you go to the premises tab, you

00:16:40

can now notice that our

00:16:42

displacement is not the same everywhere, that

00:16:44

the middle of the slab collapses in them,

00:16:52

that is, in

00:16:54

principle,

00:17:01

let's perform the second operation even

00:17:04

if the cattle you are considered us

00:17:06

so it happened that by chance it’s very good at

00:17:09

least 2 iterations always drive the

00:17:12

more the better the more accurate it is at

00:17:13

some point the essay is so

00:17:16

small that it’s not worth counting further so

00:17:19

again

00:17:23

we select the elements to which we need to

00:17:24

assign a coefficient on the style we select

00:17:26

the load ok

00:17:32

here can you do this, he will then ask you to

00:17:37

open it exists, we can clearly

00:17:39

select I

00:17:46

when we opened it next time in the second

00:17:49

operation we have this little window

00:17:51

running around we need to combine the boundaries of

00:17:53

our building with the ground conditions of

00:17:55

the site

00:17:57

for this it is best to adjust the

00:17:59

grid parameters with a smaller step

00:18:03

100 is not easy here, one by one meter

00:18:04

is sufficient

00:18:06

and we combine the boundaries so everything is easy,

00:18:10

you have a complex configuration in terms of plan,

00:18:12

naturally you will have to work a little to get it

00:18:14

done now, well, that is, we

00:18:18

have opened the existing site so that we do

00:18:20

not have to re-enter the parameters of the wells and

00:18:21

so on, again, not we forget to apply the

00:18:24

load, we

00:18:26

perform the calculation,

00:18:31

we are again updated on the values, this time

00:18:35

we are from and the minimum is 500

00:18:39

xiaomi 1900, that is, by 10 percent,

00:18:43

almost all of this was done, it was repaired,

00:18:44

in order to do another operation,

00:18:46

we save the frame diameter, we close the scene, we

00:18:49

assign the number of patients to 10,

00:18:54

and

00:18:56

we perform it again, but saving we perform it

00:18:58

calculation of more fish

00:19:21

here we already have a larger movement

00:19:23

turned out

00:19:25

below [music]

00:19:27

transfers

00:19:30

at least one more iteration let's

00:19:31

calculate how much the chic value will be

00:19:37

or are you rand and choose the plant

00:19:40

created and

00:19:46

what do I do so

00:19:49

we have a site here this is the one

00:19:52

whose blood was not attached to

00:19:54

the project they will always ask

00:19:57

to use these sites they will

00:19:59

swear not very conveniently since I make it

00:20:02

a little

00:20:03

easier where

00:20:06

you can do me as we

00:20:09

insert it apply the load

00:20:13

we do the calculation

00:20:19

so here we have all 3 herds of which

00:20:21

there are generally 1700 that is quite

00:20:25

strong the coefficients of the bed change

00:20:28

over the iterations, it won’t be enough for us either;

00:20:30

we save it for ska on the podium;

00:20:35

we assign it

00:20:39

and,

00:20:48

in general, continue like this

00:20:50

until our iteration values

00:20:53

differ by less than

00:20:56

at least for 5 cents;

00:20:58

graphical analysis last time in a day

00:21:00

if anything,

00:21:04

just look at how

00:21:06

12 millimeters of movement are already changing, and that is,

00:21:12

like things,

00:21:14

I do

00:21:39

n’t forget to put the load strong enough

00:21:50

320,

00:22:07

that is, sometimes 2 3 operations are enough,

00:22:10

sometimes 50 cm and heads,

00:22:18

but by the way, we probably don’t

the night you also know how to view

00:22:40

we have the average value in the middle, more precisely the

00:22:44

bed coefficient is 350 somewhere in there I’ll

00:22:47

hide 1200 now we’ll run this race

00:22:50

if it differs slightly from these extreme values

00:22:52

we’ll stop there

00:23:09

because there are minimum and

with the skin already 18 millimeters in the message,

00:24:29

let's go to it one last time on it, now you're getting

00:25:01

close enough to get all the values,

00:25:08

that is, this will be the last operation,

00:25:10

here we'll put a tick in the box to assign

you can see it all from 1 our center is

already 250 thousand, in principle it’s normal we

00:25:42

had 250 there too more than once already from whether

I remember 07

only here now

there is some consolidation of our soil

saved,

00:26:10

we do the final calculation

00:26:24

and in fact we end up with a

00:26:30

room of about 20 millimeters

00:26:32

in the center,

00:26:34

exactly 12 13 millimeters along the edges

00:26:40

and evenly.

You can also have a taste of the processors to see

00:27:23

we don’t have it in a

in principle, further and further it is necessary to
