Research on Shear Wall Quantity of Frame-shear Wall Structures in Earthquake Zone by Classifying the Vertical Members

摘要

The method for figuring the optimal shear wall quantity for frame-shear wall tall buildings with variable lateral rigidity a-long the height in earthquake zone is presented in this paper by means of dispersal-serial interaction method. It is for the first time to put forward the method for figuring the optimal amount of shear wall in frame-shear wall structure by classifying the vertical members. The definition of Inter-Story Drift is made clear and definite by author. A 20-storey framed-shear wall tall building is numerically examined and the results show that the method is accurate enough for use in the preliminary stage of design.
