Abstract

Abstract

The response characteristic of hyperbolic paraboloid cable-net in fire, such as displacement and inner force, have been investigated. The in-plane horizontal displacement of cable-net structure under concentrated load is small enough relative to the out-plane displacement of the cable net, which can be ignored. A simplified method, which considers the material and geometric nonlinear property, is presented to analyze the behavior of cable-net structure at high temperature. To validate the method, two models are analyzed by the simple method and finite element method (FEM). Comparisons of two results indicate that the simplified method is correct and convenient to analysis the cable net structure in fire (at high temperature).
- hyperbolic paraboloid cable net,
- structural response in fire,

- dual nonlinear
