The Application Research of Overall Spatial Truss System in a Super Long-span Cantilever Structure
The article takes a large cantilevered project as the background,conducting a comparative analysis of three different load-bearing systems for large cantilevered structures:the solid-web I-beam steel beam system,the large-span planar circular tube truss system,and the integral spatial truss system.Ultimately,the integral spatial truss system is chosen.The article systematically elaborates on its architectural features and structural layout.It performs a force performance calculation analysis using computational software.The results indicate that the integral spatial truss system is reasonably configured,achieving reasonable control of component stress ratios and a high level of structural safety redundancy while meeting the conditions of architectural functional styling.Additionally,considering the architectural styling characteristics,the article emphasizes three measures applied in this project to enhance the overturning resistance performance of large cantilevered structures.The document provides relevant design suggestions for similar projects involving such large cantilevered structures.
