Description
Summary:An incremental equilibrium equation was deduced for the construction of glass curtain system with inverted-cone curved single-layer cable-net based on the theory of non-linear finite element method. In view of actual influence of glass installation during the construction process, analysis is made on the correction algorithm for formation of non-linear stiffness matrix of structure with consideration of glass installation. The developed algorithm allows for double control over the shape and pre-tension during the construction, and accurate determination of the structural configuration and cable force. Feasibility and accuracy of the method are verified and supported by the case study results.
