Research Of Optimal Design Of Frame-shear Wall Structure Based On Seismic Performance

Frame-shear wall structure has been widely used in the high rise due to its good ability to resist the seismic behavior. The frame-shear wall system Optimal design for the reasonable stiffness of shearing walls is done. The main jobs and conclusions are as follows:(1) To calculate the objective function and constraint condition in optimization method, it presents the team-work principle of frame-shear wall structure and its structural analysis. Work out the fundamental differential equation by making use of the boundary condition to achieve the formula for internal force displacement in hinged and rigid connection system of frame-shear wall structure.(2) According to the limitation of maximum drift angle between stories of the earthquake resistant design code, it uses a computer language-VC to compile the continuous analysis principle of team work in frame-shear wall structure, which aims to the objective of minimizing earthquake. It can calculate the number of shear walls that meet the requirements. This method which is fit for the primary design of high-rise buildings in earthquake zone, is simple and practical in actual application.(3) Through the analysis and comparison of the optimal number of walls in hinged and rigid connection system of frame-shear wall structure by examples, it shows that we can also achieve the purpose of reducing the number of walls by strengthening beams stiffness in the frame - shear wall structure. It uses the computer language VC to compiles a program to solve frame - shear wall drift angle, and to prove the reasonableness of the optimization of value of the stiffness characteristics and the optimization stiffness of frame-shear wall. At the same time, it verifies the reasonableness of the optimization results with the range of basic structure of the natural cycle.
