Parametric Study of Buildings with and Without Shear Walls for Seismic Performance
Shear walls are structural systems which provide stability to structures from lateral loads like wind, seismic loads. As shear wall resist major portions of lateral loads in the lowest portions of the buildings and the frame supports the lateral loads in the upper portions of the building which is suited for soft storey high rise building. The properties of these seismic shear walls dominate the response of the building and therefore, it is important to evaluate the seismic response of the walls appropriately. In this present study, main focus is to determine the solution for shear walls behavior in multi-storey building. Effectiveness of shear walls has been studied with the help of six different models. Model one is bare frame structural system, model two is dual frame structural system and model three is a complete shear wall structural system with internal walls in y-direction and model four is a similar model having internal shear walls in x-direction, model five is again a dual frame having columns at exterior and shear walls in interior placed in y-direction and model six is also an dual frame structure having columns at exterior and shear walls at interior placed in x-direction. An earthquake load is applied to a building of G+15 stories located in zone III, type of soil II and various other factors are considered. Parameters like displacement and storey drift are calculated in all the cases replacing column with shear walls and their locations.
