STUDY ON SEMI-RIGID FRAME WITH STEEL PLATE SHEAR WALL

摘要

As a new lateral bracing structural system the Steel Plate Shear Wall is composed of steel frame and steel plate,which has many advantages such as high initial stiffness,stable hysteretic behavior,excellent ductility and energy dissipation characteristics. At present based on the assumption that beam-column connections are rigid or pinned,and few studies considering the influence of the joints on system performance. In this paper,the research results on design model,code,theoretical and experiment in recent decades are comprehensively described,and a new type of structural system is presented: semirigid frame with steel plate shear wall. In the use of steel plate shear walls as lateral support system at the same time,the system considering the performance of semi-rigid connections in the steel frame,so it can more realistically simulate the characteristics of the connection to achieve redistribution of internal forces to improve the framework of the economy,being able to meet the requirements of the structural lateral displacement to simplify construction of joints,improve construction efficiency. Examples show that for the steel plate shear wall with flush-end plate is concerned,the new system is both practical and economic.
