A STUDY ON NONLINEAR PROBLEMS OF CURTAIN WALL STRUCTRUES OF HOLLOW GLASS

This paper discusses the mechanical calculations of curtain walls of hollow glass in highrises.According to real deformation,the author deduces the corresponding control equations,probes main stiffness of hollow glass and the caluclation of reduced stiffness and discusses the internal force and deformation of hollow glass under dead load,wind load,seismic force and temperature by applying the nonlinear theories of large deflection of orthortropic slabs.The approach used in the paper is to apply the concept of method of weighted residuals and use the least square collection method to establish residual equations so that the unknown quantity can be obtained by removing residuals.
