Influence of welding deformation on anti-collapse performance of single-layer reticulated shell structures with prestressed cables

Abstract In this paper, the ABAQUS finite element software is used to model and analyze single-layer reticulated shell structure. And method of removing constraints key components anti-continuous collapse performance structure under action geometric defects welding deformation. Welding deformation mainly caused by prestressed cable tensioning shell. The results show that removal columns will lead continuous upper part, which leads whole structure, can make more obvious. Thus determining influence temperature shrinkage on performance.
