摘　　要：以中金大厦索网幕墙的设计为案例,研究了一种跨转角微曲面索网幕墙的分析和设计方法,从索网结构整体分析计算、关键节点分析、幕墙系统设计等方面提出了关键技术细节。采用“微曲面”的单层索网结构支撑的建筑幕墙,可以实现建筑立面转角的造型需求;对索网结构整体分析时,除应考虑主体结构刚度和施工过程的影响外,还应考虑索网节点处不同构件之间的空间关系;幕墙系统设计时应重点关注玻璃面板支撑点在幕墙平面内、外的位移,严格控制面板翘曲,采取措施防止面板滑移出连接件范围。Taking the design of the cable mesh curtain wall of CICC Tower as a case study,and design method of a cross-corner micro-curved cable mesh curtain wall was studied and analyzed,and the key technical details were put forward from the overall analysis and calculation of the cable mesh structure,the analysis of key joints,and the design of the curtain wall system.The results showed that the“micro-curved”single-layer cable network structure supported building curtain wall could realize the modeling demand of the corner of the building facade;the overall analysis of the cable network structure should consider the rigidity of the main supporting structure and the influence of the construction process,and should also consider the spatial relations between different components at the joints of the cable network;when designing the curtain wall system,the focus should be on the displacement of the glass panel support points in and out of the plane of the curtain wall,the warping of the control panel should be strictly controlled,and measures should be taken to prevent the panel from sliding out of the range of the connectors.
