Seismic Performance Analysis Of High-rise Frame Supported CL System Composite Shear Wall Structure

In the era of rapid economic development,the demand of people for building energy conservation,diversity and versatility is also increasing.In this paper,the high-rise frame supported CL system composite concrete shear wall structure can not only meet the needs of people for the integration of different building functions,but also meet the requirements of the green development of contemporary buildings,which is favored by more and more owners.In this paper,the seismic behavior of high-rise frame supported CL system composite concrete shear wall structure is studied comprehensively.Based on the search and study of a large number of documents,taking SATWE as the analysis software and relying on the engineering example as the background,this paper analyzes and studies the high-rise frame supported CL system composite shear wall structure by using the vibration mode decomposition response spectrum method and the time history analysis method,proves the necessity of using the time history analysis method for supplementary calculation,and verifies the reliability of the model by using ETABSBy changing the relevant parameters,including the location of the transfer floor,the axial compression ratio of the corner column of the frame column,the thickness of the upper and lower shear walls of the transfer floor,the influence rule of the internal force and deformation of the structure under the earthquake is analyzed.The results show that,with the increase of the location of the transfer floor,the period of the structure increases,the floor displacement increases,the shear weight ratio decreases,the story shear force decreases;with the decrease of the axial compression ratio,the period and story displacement decreases,the story shear force increases,the shear weight ratio increases;with the increase of the thickness of the shear wall,the period and story displacement decreases,while the story shear force increases,the shear weight ratio increases.For example,when the transfer floor position increases by two floors,the natural vibration period of the structure increases,the maximum displacement increases by about 3.5%,the interlayer displacement at the transfer floor increases by about 12%when it changes at the low level,increases by about 4%when it changes at the high level,the storey shear force decreases by about 6%,the shear weight ratio decreases,and there is no obvious effect on the vibration mode.When the axial compression ratio of the corner column of the frame strut decreases by 0.1,the natural vibration period of the structure becomes smaller,the maximum displacement decreases by about 4%,the interlayer displacement at the transfer floor decreases by about 12%,the storey shear force increases by about 39%,the shear weight ratio increases,and there is no obvious effect on the vibration mode.When the shear wall thickness increases 80 mm,the natural vibration period of the structure becomes smaller,the maximum displacement decreases by about 3%,the maximum inter story displacement decreases by about 6.5%,the story shear increases by about 10.5%,and the shear weight ratio and mode shape have no obvious change.When the shear wall thickness increases again,the change rule is the same as above,but the change range of displacement and internal force decreasesFinally,the conclusion is used to verify and analyze an engineering design example,summarize the rule of seismic performance of high-rise frame supported CL system composite shear wall structure,and put forward some guiding suggestions and suggestions for its structural design.
