Abstract

A simplified method is used to discuss the effect of structural twisting on the optimal stiffness of shear wall in tall building in this paper. First, the location of the rigidity center at any floor will be determined. Then, the twisting moment at any floor will be found out. According to the equilibrium of forces, the twisting angle of each floor will be obtained. After having the values of these twisting angles, the formulae of drift at any floor and the maximum lateral deformation of the building found out under the condition that the structural twisting is neglected can be modified easily. Next, the constraint conditions including displacement and stress constraints could be formulated again. After that, an earthquake loading selected as an objective function could be given based on the theory of response spectra. By taking the effective stiffness of shear wall as a design variable, a mathematical model for determining the optimal stiffness of shear wall is established. Finally, a practical example is given to show the effect of structural twisting on it by using this model.
