【提要】 北京融科资讯中心C座大堂是一座由柔性索网结构支承的全玻璃结构，整个结构由四根悬索支承。在大堂的施工过程中，先安装并张拉四根主悬索，然后安装立面拉索，最后安装屋顶及立面玻璃。采用有限元方法模拟分析了施工过程中索的内力变化情况。分析结果表明，在张拉过程中要严格监控索的内力和位置，保证张拉出预期的结构外形和刚度。

Abstract:The pavilion of tower C in Beijing raycom infotech park is a allglass structur
e supported by flexible cable net system,and four suspended cables are used to bear the
structure.In the construction,the four main suspended cables are fixed and tensioned firstly, then the lateral cables.The roof and the lateral glass are monitored lastly.The FEM is used to simulate the change of internal force in construction.The results show that the force and position of the cables should be monitored strictly to ensure the prospective shape and rigidity.
