With the rapid development of modern technology and economic, the type of building grow in number, the high degree of building also become higher. And the frame structure with shear wall becomes more mature. With the merits of each form, their combination is widely used in high-rise building structures, such as offices and hotels. In actual design, the structural design of the shear wall and frame design is generally based solely on experience, and then the designers adjust the structure by the computer simulation based on the specification. The process is time-consuming and blind. It is also difficult to form a unified and effective understanding of the structural design. Therefore, it’s essential to research the security and reliability at the request of the conceptual design, and improve the safety and rationality of buildings.This study does the following works at the request of the structural design and regulatory requirements: (1) Select a wide range of shear wall layout in the conceptual design criteria, and determine the framework for beams and columns according to architectural requirements. Then use the PMCAD to model the work. There are six kinds of different shear wall layout model in this study.(2) Calculate the internal forces and displacements of the frame-shear wall structure through SATWE, and judge the reasonableness of each shear wall layout at the request of the specification on the shear weight ratio, weight ratio, circle ratio and displacement ratio. Then select two most suitable shear wall layout models.(3) Finally, give a more in-depth elastic-plastic time history analysis using the software of the PUSH&EPDA, compare the inelastic displacement ratio, information about the weakest node, the plastic hinge and the inelastic displacement seismic waves of the two models.
