Conceptual design of a building with columns and shear walls

1) Ans :-

     Structure A is well designed of the torsional forces than compared to the structure B and structure C, here the l-shaped walls provide stiffness at The corners of the structure which prevents the twisting of the structure resisting the lateral forces in the both directions and in structure B and C there may be the cause of the bearing failure occurring at the corners due to the heavy lateral force acting on the structure.

     With respect to the eccentricity the redundancy of the structure A and B is more than compared to the structure C as structure A and B are symmetric over the cross section on the both sides whereas the structure is symmetric over in one direction only which makes the structure weak in That particular direction of the lateral loads.

     And in the structure A provision of the L-shaped walls are very ideal for the high stiffness and strength achievement and its cost of the construction will be more than compared to that of the vertical walls present in the structure B and structure C.

      constraints: structure A is best as the shear walls are placed at the corners which does not interfere the openings of the structure whereas the structure B and structure C has the shear walls at the middle of the face where architectural constraints are interfered.

2) Ans :-

• As shown in the figure given above the eccentricity of the structure along the y-direction is more than compared to that of the x-direction along

• This eccentricity can be reduced by the provision of the shear walls ideal to reduce the eccentricity of the whole structure which makes the Structure torsional stiff.

• In the figure the beams are not continuing from span to span which is interrupting the free flow of the beam internal forces beam which not supported the column is not providing the enough lateral stiffness to the structure.

3) Ans :-

- The general layout and the geometry of the individual plane will be having the vital role in the seismic behavior of the whole structure. So, it is important to consider the layout of the structure.

- As a structural engineer it is important govern the important geometric details of the individual plane frames And check for the cost effectiveness Of the frame.

- Provision of the waffle slabs as the slab for this place would make the structure more resistant for the lateral and the vertical loads.

- Can also consider the flat slabs.

- For the foundation consider the raft foundation.
