大跨度张拉结构风致动力响应研究进展

大跨度张拉结构的风致动力响应具有几何非线性明显和风与结构的耦合作用不可忽略等特点，对这一问题的研究具有较大的理论难度，一直是风工程领域关注的焦点。据此结合作者及其梯队近年来所做的工作，介绍了国内外在悬索和薄膜结构风振分析领域所进行的理论研究、实验分析和数值模拟方面的研究进展，并着重介绍了薄膜结构在考虑流固耦合作用下的气动弹性性能研究。

Overview of Wind-induced Response for Large-span Tension Structures

The analysis of large-span tension structures represents a highly geometrically non-linear problem,whose analytical solution is very difficult to obtain.Moreover the interaction effects between the loading process and the response process have to be considered.This paper first overviews the study on wind-induced vibration for large-span tension structures by means of geometrically non-linear random vibration methods.In the second part of the paper,a simplified aerodynamic model,based on wind tunnel test,was proposed.Finally,the technique of computation fluid dynamics(CFD) was introduced to predict the values of wind forces and wind-induced response by means of numerical simulation.
