Structural Modelling using Etabs 2018

Aim:

To create a model of G+7 residential 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 by using the dimensions given in the architectural plan using grids and storeys.

Material properties are added such as grade of concrete, rebars and shear reinforcement.

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 3.6 KN/m.

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 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.
