Abstract: The steel roof of Yangzhou Diving and Swimming Center is a long-span space hybrid-structure, including bidirectional planar trusses, monolayer lattice shell and bidirectional cable trusses. rllus article primarily introduces modal nalysis, nonlinearloading analysis of the whole structure, staged construction and so on. The results and conclusions presented can be used for references in design of similar projects.
Keywords: long-span hybrid space-structure; cable truss; nonlinear analysis; staged construction
