Modeling of Asymmetric Shear Wall-Frame Building Structures

Abstract

Based on the conventional wide column analogy, two different three-dimensional shear wall models for open and closed sections are proposed. These approximate models are verified in comparison to not only the results available in the literature but also the ones obtained by using models containing shell elements. With the help of these new models five different groups of shear wall-frame structures with different floor plans and different heights are analyzed. The first three natural vibration periods are determined and time history analyses are performed. The results of these computations are observed to be in good agreement with those obtained by detailed models containing shell elements.

Effect of Shear Wall Shape on Seismic Response of RC Building Frames

“…The results obtained from this study show that building with shear wall can effectively improves the stability of the structure under seismic loads. Akis et al [2] examined asymmetric shear wall effect in building by considering two approximate shear wall models, for open and closed sections, based on the conventional wide column analogy. In this study three dimensional analyses of open section shear walls modelled by the conventional equivalent frame model resulted into serious errors especially in the analysis subjected to torsion and the finite element modelling becomes stiffer compared to the conventional equivalent frame model.…”
