［摘要］对淮安大剧院单索幕墙支承钢结构空间三维建模、截面选择、计算分析、支座节点以及对主体混凝土结构作用进行了系统的介绍。用合理的简化方法解决了复杂体形大跨度空间结构的建模问题，包括根据建筑立面要求选择结构合理的截面形式；同时对单索预应力的整体模拟提出符合工程要求的简单准确的方法。最后对支座节点进行了分析，研究了支座对主体结构的破坏特征，并根据其传力路径进行合理可靠的加强措施。

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
