Abstract

Objectives: The current study intended to compare the geometry and location of shear walls on regular and irregular structures. Method: Using the software Response Spectrum method in ETABS, the dynamic parameters of irregular and regular structures with varied shear wall positions have been compared in this research. Findings: The output completely favours the system with shear wall rather than the system without a shear wall. The oscillation period of the RC frame structure with the shear wall is reduced by 50% to 60% when compared to the oscillation period of the RC frame G+14 multi-story structure without a shear wall. Stiffness and dynamic parameters also favour Regular buildings with the shear wall. Novelty: The novelty of this work is the comparative study of regular and irregular structures by considering both the parameters like the location of the shear wall along with geometry and material nonlinearity.
