摘　　要：中国石油大厦工程的东、西立面中庭索网幕墙用ANSYS有限元分析法分析单层索网的结构力学特征,并用倒拆法进行索网结构的终态考虑和施工过程模拟计算。文章对该复杂柔性支承结构体的设计及施工过程进行详细介绍,包括在考虑预应力、几何非线性及边界条件的影响下,对荷载工况、承载能力、变形能力及施工张拉过程的模拟计算等。This paper used ANSYS finite element analysis method to analyze the single-storey cable net structural mechanical characteristics of the atrium cable-net curtain wall on east and west facades of Petro China Building project. Inverted disassemble method was used for final state consideration and simulative construction computation of the cable-net structure. Design and construction process of this kind of complex flexible supporting structure were introduced in details, including simulative calculation of load calculation condition, bearing capacity, deformability and stretching process, with consideration of the influences of prestress, geometrical nonlinearity and boundary condition.
