STUDY ON OPTIMAL SHEAR WALL QUANTITY OF FRAME-SHEAR WALL STRUCTURES IN EARTHQUAKE ZONE

摘要

The method for figuring the optimal shear wall quantity for frame-shear wall tall buildings with variable lateral rigidity along the height in earthquake zone is presented in this paper by means of dispersal-serial interaction method. It is 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 the 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.
