| In order to carry on the project construction safely, economically and smoothly, the structure is required to be sure of the rational construction sequence according to the objective conditions. As a result it is necessary to make simulation analysis on the construction process of the large space steel structure, so as to realize the mechanic features of structure, as well to as research a series of relevant problems in construction stage.Taking the project of no-station pole canopy in Fu yang for example, based on the research on large span space structure at home and abroad, this thesis analyzes the mechanic features of space steel structure in construction stage and the integral dynamic response, and consequently put forward control measures in the construction process of large space structure. Through the research, some valuable conclusions will be attained; some research results will be applied directly to the installation of no-station pole canopy which will remarkably improve the proficiency of construction, economize the investment, shorten the period of constructing but at the same time satisfy the quality. The abstract is as follows.The static analysis of no-station pole canopyWith the finite element software MIDAS/CIVIL, a 3D finite element model of no-station pole canopy, very like the actual construction, is built, which is used to make a simulation analysis on the hoisting of column and key truss, find out the rational cut mark and the vertical location and calculate the camber of key truss. After that a rational construction plan comes out, which is applied to the construction.The dynamic response analysis of no-station pole canopyIn this part, modal analysis method, response spectrum as well as time-history method will be used to calculate the integral dynamic response and seismic resistance and deformation. The calculating result demonstrates that no-station pole canopy has strong vibration resistance and high structural deformation capacity.
