Plane Finite Element Analysis And Lateral Stiffness Analysis Of A Shear Wall Structure With Partial Supported Frame

In recent years,with the development of our economy and the expansion of the population,expanding the scale of the modern architecture,people are increasingly demanding the use function of buildings,the direction of the modern building toward multi-function,multi-purpose development.Among them,the high-rise structure with transfer story can satisfy the requirement of the lower part of large space building function,but the transfer sites easy to cause the abruptness of lateral stiffness,the vertical component of the upper and lower intermittent discontinuity,conversion component complex loading,the need for lateral stiffness and mechanical characteristics of the transfer sites is particularly concerned in the design.At present,many studies on regular plane structure,but few studies on the long irregular plane structure with end conversion.In this paper,a variety of computational models are used to calculate the structure of the whole and part to review the lateral stiffness.Because of the complexity of stress,detailed finite element analysis of the bearing condition of conversion components is needed in the design.In this paper,a high-rise shear wall structure with end conversion was taken as an example,combined with performance-based seismic design requirements,we carried out the following aspects of work and got the appropriate conclusions.1.Using SATWE program to analyze the structure’s response spectrum analysis and elastic time-history analysis under frequent earthquake,evaluating the whole structure.The results show that the Seismic performance of the whole structure under frequent earthquake accord with the specification limits.Response spectrum analysis and elastic time history analysis results has consistency and regularity.2.To further study the lateral stiffness of conversion parts,we check the lateral stiffness of conversion parts as an isolation body,the results show that the lateral stiffness of conversion parts as an isolation body meet regulatory requirements.3.Using FEQ program to conduct finite element analysis of conversion component,and we analyze in detail the stress distribution of conversion component under vertical load and horizontal load,the actual project could take most poor value reinforcement according to the results of stress analysis.At last we toke a simple discussion on the design of frame supported shear wall.4.Using Pushover program to conduct static elastic-plastic analysis of the structure under rare earthquake,evaluating the structure’s seismic performance under rare earthquake.According to the calculation and analysis,for meeting the project’s characteristics and requirements of the seismic performance objectives,we put forward specific measures to strengthen the structural seismic.
