High-rise Frame Shear Structure Shear Wall Seismic Design And Case Analysis

Frame shear structure set the framework structure and shear wall structure advantages and common under vertical and horizontal load, with strong seismic ability and the ability to resist horizontal loads. Frame shear structure of structure Structural lateral displacement is designed for one of the major problems, and the role of the earthquake structure Structural lateral displacement far outweigh the wind load under the action of lateral, so as to reflect the frame shear structure is the design key of seismic design.Frame shear structure with its good seismic performance is widely used in our country of the high-rise building, the frame shear structure of shear wall is the main lateral force resisting member, almost bear the total horizontal seismic action of more than80%, due to the shear wall stiffness is bigger, the number and arrangement of structure is not the same as the whole stiffness and just heart position affected, and at the same time, the size of the shear wall stiffness will directly affect the safety of structure and engineering cost, so deal with shear wall quantity and arrangement is a framed-scissors structure design of the most important problems. This paper according to the frame shear structure own stress deformation characteristics and frame shear structure frame and shear wall collaborative working principle, the engineering example of the shear wall quantity change from few, by changing the process of optimal respectively established three-dimensional composite structure finite element analysis model, and according to the theoretical analysis of the three different shear wall under the arrangement, the calculated results have chosen arrangement of shear wall quantity optimal engineering example. In addition SATWE using finite element analysis software example of shear wall aseismatic optimization analysis, considering the layer displacement Angle and lower layer stiffness ratio, torsion cycle and translation cycle, the ratio of frame and shear wall resistive overturning moment and the ratio of building security and related data, and through the production of the form and the chart, illustrated the aseismic optimum analysis, obtains shear wall optimal layout and seismic analysis integrated optimization design, not only meet the seismic requirements, and tend to economic rationality.
