Analysis and Comparison of Different Lateral Load Resisting Structural Forms

Abstract

Nowadays there has been a considerable increase in the number of tall buildings. In one or the other residential and commercial buildings, there is always a trend towards taller and more slender structures. Here, in this present work a particular type of irregular building with different structural forms are considered and seven models are developed in Etabs software with codal provisions. These models are analyzed for response spectrum method and wind load. When seismic analysis is considered some of the major factors come into picture like lateral displacement, storey drift, and stability of columns in particular storey due to lateral forces and when the building is in irregular configuration torsion irregularity will also become an important factor. In this present work all this points are considered and the results obtained are tabulated, graphs are plotted and compared. The results shows that the tube structure and 'L' shape shear wall are more stable and does not have torsion irregularity and also the displacement is less compared to other general structures. Drift can be controlled by providing outrigger at optimum location of the building.
