Steel structure integral hoisting method based on BIM
According to the present invention, a steel structure integral hoisting method based on BIM comprises: calculating member deflection by using BIM software, determining an arching degree of a single truss, checking member deflection in construction, comparing the member deflection in construction with a pre-arching degree, and comparing a deflection degree after loading that follows completion of construction with designed control deflection degree requirements; using an MIDAS finite element analysis plug-in to set hoisting points at intersection of an upper chord and a diagonal web member on the truss and on each truss, performing design calculations of lifting lugs, and analyzing displacement of structurally critical nodes; performing manual or automatic layout on the integral steel truss, steel tubes and steel cables in a venue model, performing integral analysis on the steel truss of the steel structure, calculating pre-stress of each node of the integral structure by using the BIM software; finally, virtually adding an environment and roads of a construction site by using the BIM software, completing stimulation of a whole erection process, determining the installation time and the situation of occupying construction roads of each steel truss, and estimating construction completion time. The present invention solves the construction problem of limited space, reduces the construction cost and shorten the construction period.
