Structural Modelling using Etabs 2018

AIM :

To create a model of g+7 building given in the arhitectural drawing as per the provisions of IS 1893 and IS 13920 followed by response spectrum analysis.

PROCEDURE:

> Plan is plotted according to the dimensions given in the architectural plan using grids and storeys.

> Now the material properties are added such as grade of concrete, rebars and shear reinforcement.

> After this the section properties are added such as size of columns ,beams ,slabs and shear walls.

> Columns and beams along with shear walls are placed in the plan as shown in figure and pier labels are assigned.

> Brickwall load is apllied to all the beams of 3.6kn/m.

> Now live load is assigned to the slabs as per the provisons of IS 875 and reduction factor is assigned.

> Live load on the roof is applied less compared to other storeys.

> Now different load combintions are assigned followd by mass source and diaphragm.

>Now it is checked for response spectrum analysis.

> Deformed shape of the model is obtained.

> Values for the base reations are obtained.

> Story response plot is analysed as we can see that the drift is within the permissible limit i.e 4% in both x and y direction.

> Now base reactions due to shear wall  is obtained in x and y direction.
