The Analysis Method Of Seismic Resistance Behavior Of Concrete-filled Steel Tube Shear Wall With A Set Of Column Structure

High-level frame structure is good at aseismic performance and wind resistance, good at economic structure, with the rapid development of the high-level structure, the core tube of shear wall has become the focus of engineering and academia.In practical engineering, especially high-level and super-tall structures system designing, the shear wall of the cylinder composed of most of the earthquake. The structure of the seismic performance depends on large part of cylinder body, therefore, it must take effective measures to ensure the cylinder bearing capacity and ductility. To improve the seismic behavior of shear wall is a kind of concrete-filled steel tube column using exhaust shear wall. For the study, the seismic performance test of theoretical research and design method. This line of concrete-filled steel tube column shear wall, this new type of shear wall structure as the research object, of concrete-filled steel tubular frame shear wall cylinder column row overall structure anti-earthquake performance and monolithic column steel concrete shear wall in the level of reciprocating load is analyzed, the damage for steel tube concrete column frame shear wall structure system is in this new cartridge, the popularization and application in engineering. This article mainly from the following several aspects and that the relevant conclusions:(1)Through the literature on the mechanical properties of concrete filled steel tube characteristics are analyzed and summarized, including the steel and concrete work together and dynamic performance of concrete filled steel tube.(2)Concrete finite element theory illustrates the concrete filled steel tube column frame shear wall structure of the platoon finite element analysis methods and steps.(3)For the concrete-filled steel tubular frame shear-wall with a set of column structure and the reinforced concrete shear wall structure modal analysis, seismic response analysis, the single chip shear wall structure under the earthquake effect again the destroy form of dynamic response analysis, comparative concluded. include:a. Application of the finite element analysis software ANSYS in two different structures scheme conduct modal analysis, this paper compares the vibration period and strikeout characteristics.b. Along the X, Y direction respectively 8 degrees input earthquake acceleration response spectrum analysis, the standard of two schemes calculation in the X, Y direction of seismic response. In comparison of the floor displacement, shear and moment.c. Enter the same wave, the comparison of the two kinds of single chip shear wall structure in the same under seismic damage model and form.(4) Take two model of single chip shear wall, the research on low load and level of shear wall failure pattern and law, ductility development situation.
