Abstract

Objective: Objective of this study is to find variation of parameters displacement, story drift, fundamental time period, base shear and column force with respect to geometry of building and of column. Methods/Statistical Analysis: Response spectrum analysis was done for all the models using ETABS software and all the above parameters are extracted from all the models including one reference model with rectangular geometry. All the models generated are compared with that of the base or reference models and the results are stated. Findings: It was found that the story drift was maximum at the bottom of the structure when compared to the above stories so as the displacement. Circular columns are found to have increased base shear when compared with remaining models. Improvements: Masonry in-fills induces stiffness which reduces the stiffness of the structure which decreases the displacement of building so inclusion of masonry in-fills can improve the stability of the building
