| Abstract: | In accordance with the characteristics of the configuration and behavior of arched corrugated metal roof,it was simplified into a kind of plan arch structure in theory.Based on a great deal of geometrical nonlinearity analysis,and linear regressive treatment on the theoretical results,the formulas for the elastic stability load\|bearing capacity of this kind of structure with distinct support conditions,varying rise\|to\|span ratios,and under different loads were derived.These formulas apply to not only arched corrugated metal roof but also to any other kind of circular arch structure. |
