The Analysis and Application Research on the Space Work of Portal Frame

Abstract

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.
