Project 2 - MODELLING, ANALYSIS & DESIGN OF COMPOSITE STUCTURES IN COMFLOR & ETABS

SOLUTION:-

Frist down load the project one auto cad file and inport in autocad

then draw the center line of each column then go to the etabs

2. Then go to the etabs and set the story height and grids follow the auto cad center line dimention

3. then define the materials like concrete rebar and steel

4. now define the section property like composit column steel beam wall and deck slab

5. then draw the column and beam and slabs in the etabs and check the module all thing the ok or not

6. Then define the load pattern

7 then assign the dead load and live load base reaction

8. then calculate the loads

`A_h=(Z/2)*(I/R)*(S_a/g)`

where z=0.16 , I=1.5

R=4

`V_zeta=A_h*W`

w=sesmic weight

sesmic weight=DL+0.25LL+0.5LL

KANPUR ZONE -3 , 0.16

`T_a=(0.09h)/root_d`

h=90.5m

d=37.5m

then Ta=1.33

then follow the IS table and calculate the value of `S_a/g`=1.02

Ah=0.0306

now calculate the Vu find the base reaction and calculate this value

Vu=67170.13KN
