In this article, a study is made on multi-storeyed buildings of a symmetric plan with shear walls provided at multiple locations across the plan, and linear static, linear dynamic and non-linear static analyses are performed.Abstract:
Multi-storeyed buildings are popping up more and more in India due to its ever-growing need for accommodation as opposed to its subsequent lack of land area. It is a known fact that as the height of the structure increases, lateral loads become a crucial part of the design. Shear walls are among one of the most common, cheap and effective methods by which lateral loads are resisted. In this paper, a study is made on multi-storeyed buildings of a symmetric plan with shear walls provided at multiple locations across the plan. The total length and thickness of walls were kept constant throughout all cases. Straight walls and L-shaped R.C.C. walls were made use of. Linear static, linear dynamic and non-linear static analyses were performed. Comparisons were made based on roof-level displacement, drift, stiffness of structure and ductility to find the best-performing configuration.read more

TL;DR: In this article, the modal pushover analysis (MPA) procedure is extended to unsymmetric-plan buildings and the seismic demand due to individual terms in the modality expansion of the effective earthquake forces is determined by nonlinear static analysis using the inertia force distribution for each mode, which includes two lateral forces and torque at each floor level.
