［摘要］石家莊國(guó)際展覽中心采用了大跨度雙向懸索結(jié)構(gòu)，其中主懸索采用自錨式構(gòu)造平衡端部水平力。該雙向懸索結(jié)構(gòu)體系在國(guó)內(nèi)應(yīng)用尚屬首次。介紹了如何結(jié)合不同的找形分析技術(shù)實(shí)現(xiàn)與建筑造型的契合及結(jié)構(gòu)的過程控制。通過研究本項(xiàng)目索結(jié)構(gòu)的構(gòu)造和受力特點(diǎn)，有針對(duì)性地提出了一種高效找形算法和一套融合找形、建模及分析過程的變形控制策略，并取得了很好的成效。

Abstract:A bidirectional large-span cable system was used in Shijiazhuang International Exhibition Center, in which a self-anchored mechanism was used to balance the horizontal forces at the end of the main cables. It is the first time that the bidirectional cable structural system was adopted in projects in China. How to use comprehensive form-finding methods to realize architectural shape of the building and control the deformation of the structure was introduced. By studying the structure and mechanical characteristics of the cable structure of this project, an efficient form finding algorithm was proposed as well as a set of deformation control strategies that integrated the process of form finding, modeling and analysis, and achieved good results. 

Keywords:Shijiazhuang International Exhibition Center; bidirectional cable; form finding; deformation control; simulation analysis; large-span structure
