Abstract:In order to analyze and assess the dynamic response of pointsupported curtain wall flexible structure due to wind buffeting forces, a timedomain calculation method is given, which links a series of simulated wind quasistatic loadings to a nonlinear finite element program. Compared to equivalent frequency domain results, timedomain solutions have a good agreement of structure modes and reflect the nonlinear character.  Two plans of
 a project of flexible pointsupported curtain wall are studied with the method and the dynamic coefficient is compared with the value calculated with the method of technical code. Conclusions about windresistant design and analysis of flexible pointsupported glass curtain wall are drawn.
