Overall Reliability Assessment of Portal Frame Structure with Roof Beam Outward Offset

Abstract:

This article deals with the condition that the roof beams of portal frame are outward offset beyond the standard limit, determines the most unfavorable position of the portal frame structure under the load and establishes the criterion standard of structural failure based on the space overall finite element analysis. It adopts Monte-Carlo method in reliability analysis methods to realize the overall reliability analysis of the portal frame structure with the roof beam outward offset. Analysis shows that the actual structure is at safe state under the design load and the reliability conforms to the standard requirement.
