Studies of Anti-disaster Ability of the Plate Truss Structure

摘要

The grid structure often overall failed duct to local damage under the disaster load. In order to avoid the situation, the load cases of the plate truss structure under vertical load are analyzed in this paper. Taking the measure of strengthening the important bars, the ultimate bearing capacity of the structure is improved significantly. The improved load bearing capacity plays a positive role in resisting exceeding loads. Anti-disaster ability of the structure is improved.
