【提要】 北京融科資訊中心C座大堂是一座由柔性索網(wǎng)結(jié)構(gòu)支承的全玻璃結(jié)構(gòu)，整個結(jié)構(gòu)由四根懸索支承。在大堂的施工過程中，先安裝并張拉四根主懸索，然后安裝立面拉索，最后安裝屋頂及立面玻璃。采用有限元方法模擬分析了施工過程中索的內(nèi)力變化情況。分析結(jié)果表明，在張拉過程中要嚴(yán)格監(jiān)控索的內(nèi)力和位置，保證張拉出預(yù)期的結(jié)構(gòu)外形和剛度。

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.
