Abstract

Shear walls are one of the most effective methods of resisting these lateral forces caused by seismic or wind load. The placement of these walls can be very influential on how the structure behaves. Since the end return of a shear wall is perpendicular to the lateral force, it is neglected for the purpose of resisting later force. This study will investigate whether or not the effect of end return on the rigidity of shear walls can be neglected. Two different building frames will be modeled using Finite Element Analysis software to see how they behave differently. Hand calculations will also be incorporated to check and verify the results obtained by the computer models. The moment of inertia is expected to be an important factor calculating the deflection of the shear wall due to bending, and the end return may significantly impact the magnitude of the moment of inertia. The objective of this study is to determine the effect of the end return on the rigidity of a shear wall.
