Influences of Sag-to-Span Ratio and Pre-Stress of Cable on the New Hybrid Structure Composed of Truss Strings and Shell

Based on the Erdos Dong-sheng Exhibition Center’s structure system, this paper uses finite element analysis software SAP2000 to do integral analysis of a new hybrid structure composed of truss strings and shell. The effects of different sag-span ratios and initial pre-stresses on mechanical behavior and the steel consumption of 11 truss Strings integral Structures are analyzed. Besides, the study may be referable for the design and research on truss strings structure.
