Analysis and Design of Micro-Curved Cable Net Supported Curtain Walls Crossing Corners

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.
