Elastic-Plastic Seismic Responses Analysis of Steel Space Grid Box Tube-in-Tube Structures
摘要
Abstract
In order to study the elastic and plastic properties of space steel grid cassette tube-in-tube structures under the earthquake actions,numerical model was built by MIDAS software,elastic time-history analysis and elastic-plastic time-history analysis of the structures under rare earthquake actions were performed.Comparative analysis of the time history curve of the top displacement of structure,the time history curve of the base shear force and the floor displacement angle was carried out.Plastics hinge damage process of the structure and the structure plastic hinge development and the yield order of members were obtained by the elastic-plastic reaction analysis.The results show:seismic resistant lines of the box tube-in-tube structure is clear,which conforms to the theory of performance-based seismic design method.关键词
