In this paper, the application of finite element software with the actual structure of the field static load test for the engineering background, describes the space effect of portal frame under vertical load. Established a gymnasium mode of portal frame through the finite element software, quantitative analysis the space effect under the vertical load, and studied the spatial interaction of longitudinal anti-lateral component to the overall structure, and compared with the results of the field static load test. The calculation results show that, the reduction of spatial effect to internal forces under the vertical load should be considered in design. It is important that a reasonable increase in rigid tie and support can enhance the space effect of the whole portal frame.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
