Seismic Analysis and Design of Multi Storey Building with Non Parallel Shear Wall System

Shear wall systems are one of the most commonly used lateral-load resisting systems in high-rise buildings. Shear walls have very high in-plane stiffness and strength, which can be used in structures to resist the effects of gravity loads and story shears due to wind or earthquake forces, making them quite advantageous in many structural engineering applications. There are lots of literatures available to design and analyse the shear wall. However, the decision about the non parallel shear wall system in multi-storey building is not much discussed in any literatures. In this present study, the main focus is to discuss the effectiveness of shear wall has been studied with the help of three different models. Model one is bare frame structural system and the other two models are with parallel and non parallel shear wall systems. An earthquake load is calculated and applied to a building of five stories located in zone V. Response spectrum analysis was performed using ETABs v 9.6 and SAFE v 12.1.1 software packages. Shear force, bending moment, base shear, time period, story drift and displacement were computed in all the three cases and location of shear wall was established based upon the above computations.
