Transverse force study of single box multi-chamber with corrugated steel webs
摘要
Abstract
The transverse span of a single-box multi-chamber corrugated steel web is large, while the stiffness of a corrugated steel web is relatively small and its transverse force is more complex than that of a single-box single-chamber box beam. Through a test was carried out for a test beam with a single-box double-chamber corrugated steel web in the elastic stage,the distribution of the beam roof′s transversal internal force was analyzed. With con-sideration to the influence of lateral and distortion bend,an energy method was applied in order to establish a cal-culation model for the transversal force of the single-box double-chamber box beam with a corrugated steel web. Ad-ditionally,the results was obtained by this energy method, test results, and results obtained by the finite element method,were analyzed in order to obtain their parameters. The analytical results showed that the impact of the in-termediate web thickness on the roof′s transversal internal force cannot be ignored. The roof′s transversal internal force in the single-box multi-chamber box beam with the corrugated steel web, decreased with the increase of the linear stiffness ratio between the web and the roof plate.关键词
