Analytic Method of Mechanical Performance of Plane Cable Net Under Uniformly Distributed Load/Wang Jianjun1,2,Liu Junjin2,Wang Cuikun2,Chen Zhanghua1 (1 School of Applied Science, University of Science and Technology Beijing, Beijing 100083,China;2 Institute of Building Structure, China Academy of Building Research, Beijing 100013,China)
Abstract:The outplane stiffness of the curtain wall supported by the tensioned plane cable net is mainly provided by the initial tension force and the elongation of the cable. The structure's geometric nonlinear characteristic must be considered when investigating the mechanical performance of the plane cable net under loads. The formulas of the tension in cable and the deformation of the cable net under uniformly distributed load have been deduced by the analytic method. It may be convenient for engineers to design a plane cabl
e net in conceptual phase.
