Enhancement Measures of 35.6m Span Arched Corrugated Steel Roof

Arched Corrugated Steel Roof (ACSR) is a kind of thin-shell steel structure. Although it has many advantages, the characteristics of little span and low carrying capacity make such structure a very narrow range. This paper take an example with an arched corrugated steel roof of the 35.6 m span constructed with traditional way but the bearing capacity can't meet the design requirements, puts forward two enhanced measures, namely design the arch into fixed end support or set concrete cantilever beam to reduce arch span, then respectively analyze the two enhanced measures with finite element analysis software ABAQUS and ACSR software, finally get the maximum stress ratio and displacement of the structure, and consider setting concrete cantilever beam as the most appropriate measure to the project. The result of this paper provided beneficial reference for the application of the same type structures.
