NEW DEVELOPMENTS OF SEVERAL ISSUES OF SPACE STRUCTURES

摘要

According to the properties of space structures, several particular issues are studied, such as seismic behaviors and analysis method under multiple support excitations, the most unfavorable loads of single-layer shells subjected to simple dynamic loads, and form finding method of space cable roofs, so the paper is the sum of three parts. The first part includes five sub-subjects, they are test and analysis of AMECC) hangar, space coherency function model of vertical ground motion, research on the multi-support response spectrum method, engineering application of various analysis method to the structures, and elastoplastic seismic response analysis, respectively. The second and the third parts are concerned with only one subject respectively. New developments of above subjects we obtained are introduced in detail.
