Three Dimensional Analysis of Shear Wall Multi Storey Buildings

Abstract

<p>The thesis studies the importance of torsion in multi storey buildings haying asymmetric layout of shear walls. A method of three dimensional analysis based on the continuous approach has been developed. The problem of torsion in a two wall core structure has been examined in detail including a test on a plexiglas model. The method of analysis presented in this thesis is general enough to deal with buildings with a large number of shear walls in plan and allows variation of structural properties along the height of the building. A number of representative examples are worked out to demonstrate applicability. The use of the method in studying the dynamic properties of multi storey buildings is shown. The response of a torsionally unbalanced building due to the application of a bidirectional earthquake is examined. Based on these results, recommendations are made on the structural behaviour of such buildings.</p>
