［摘要］石家莊國際會展中心項目建筑造型新穎別致，結構體系復雜。采用了雙向懸索結構體系，其中縱向主承重結構采用自錨式懸索結構、橫向次承重結構采用雙層索桁架結構，傳力方式特殊，施工難度大。為保證工程建造安全順利地進行，首先對石家莊國際會展中心的結構體系進行了闡述，分析了該體系的構件組成和受力特點； 其次對施工順序進行了研究，分析了施工順序合理劃分的理由，對比了不同施工順序的優(yōu)缺點； 然后利用有限元軟件ANSYS對施工過程進行模擬分析； 最后再將模擬分析的結果與實際的監(jiān)測數據進行了對比，結果顯示，模擬分析結果與監(jiān)測數據吻合度較好。研究結果為實際施工提供了施工控制參數,可指導實際施工的順利進行。

Abstract:Shijiazhuang International Convention and Exhibition Center project has a novel and unique architectural shape and complicated structure system. The two-way suspension cable structure system is adopted, the longitudinal main load-bearing structure adopts self-anchored cable suspended structure and horizontal secondary load-bearing structure adopts double-layer cable truss structure and the structure has special force transmission method and is difficult to construct. To ensure construction safety and smooth, the structural system of Shijiazhuang International Convention and Exhibition Center was first described, and the component composition and force characteristics of the system were analyzed. Secondly, the construction sequence was studied, the reasons for the reasonable division of construction sequence were analyzed, and the advantages and disadvantages of different construction sequences were compared. Then the finite element software ANSYS was used to simulate and analyze the construction process. Finally, the results of the simulation analysis were compared with the actual monitoring data. The results show that the results of simulation analysis are in good agreement with the monitoring data. The research results provide the control parameter for construction, and can guide the smooth progress of actual construction.
