Mechanical Properties and Calculation Method for Monolayer Cable Net Glass Curtain Wall under Fire Conditions

Abstract:

The developing trend of large scale curtain wall structure system is monolayer cable net glass curtain wall, so it’s important and necessary to study the corresponding calculation method and mechanical properties under fire conditions. The changing rule of the displacement and the maximum cable force with the temperature was analyzed by making series of numerical calculations, and the principle for determining critical temperature was deeply discussed upon the basis of the numerical simulation results. The critical temperature table considering different spans, grid dimensions and cable diameters is given, and the influence on critical temperature has also been studied when initial prestressed force of vertical cable is relatively small. Some suggestions are proposed finally.
