Abstract: Three-dimensional model of supporting steel structure with single-layer cable curtain wall, selection of sections, computational analysis, supporting joint and their influence to the main concrete structure of the Huaian Theater are introduced. Modeling problem of the complex shape large span space structure was solved by adopting rational simplified method, including the choice of reasonable structure according to the requirements of building facades of the section form; the integral simulation method of single prestress was proposed according with the engineering simple and accurate requirements.Finally,the supporting joint and the influence of its reaction to the main structure were analyzed, and reliable strengthen measures was adopted according to the force transfer path.

Keywords: Single-layar cable curtain wall; steel frame; self-balanced prestress,;twisted cross section; joint analysis
