Wind tunnel tests of rigid and aeroelastic model were carried out to investigate the influence of windward sudden opening on static and dynamic wind load for flat roof structures.

Finite element analysis of static performance of roof structure with circular steel tubular arch-truss;

Parametric study of roof-isolation in roof structure;

Research on equivalent static wind loadings of large-span roof structures;

Analysis of wind-induced dynamic response of the steel roof of Wuhan Gymnasium;

Beam string structure and spatial truss structure are both adopted in its steel roof.

Elasto-plastic time-history analysis for the integral structure of the steel roof structure and its RC substructure subjected to three dimensional earthquakes is carried out with finite element analysis program ANSYS.

In this paper is introduced a design system fully automatically optimized for steel roof structure developed on the basis of The Standard Drawings of Steel Roof Structure.

Arrangement and conformation of the steel structure roof are introduced first.

There are two diffenrent opinions in analysing this structure style:the first is the entire model with stand and roof,and the second is the individual model of steel structure roof.
