The Research On Quantity Of Ground Walls In Tall Frame Shear Wall Structures

A senior frame shear wall structure is a kind of typical conversion layers with high-rise building system, it can better satisfy people to use on the function of the architectural structure, with the other irreplaceable function advantage, this makes it in our country and the world get very widely.At the top of frame shear wall structure is the large shear wall structure stiffness, the lower is flexible and have a small frame structure stiffness, the whole structure in the middle of the conversion of rigidity changes significantly layer. Frame shear wall structure as a typical "soft" on the structure of the seismic performance is poor. In order to increase the overall structure anti-earthquake performance, structure layout, the shear wall structure on the ground and transfixion part to base form ground shear wall. For some shear wall ground frame shear wall structure, the team can be simplified calculation model for:to convert layer, the upper and lower for the shear wall structure of frame-shear structure to relax, two substructure method in the original node calculation method based on its improvement. Because the arrangement is to reduce ground shear wall structure and improving the structure of vertical stiffness mutations overall lateral ability, so the main measures of shear wall ground quantity influences the aseismic capacity. By using SATWE structure analysis software build box of shear wall structure model, a comparative analysis of data, after landing shear wall that quantity and bottom box pillar section area size and the number of supported. A layer of frame shear capacity, floor between layers of the maximal displacement and layer than control, deduced the minimum shear wall, ground is sure reasonable ground shear wall stiffness calculation of rational number, further through example verified the feasibility of the method.
