摘　　要：本文介绍一种新型雨篷，是由斜拉钢管混凝土空间桁架和大跨彩板拱形结构组成的联合结构。基于这种结构的非线性特征，并且考虑风与结构的耦合作用，应用随机风荷载模拟方法，研究新型雨篷结构在随机风荷载作用下时域内非线性风振响应。This paper introduces a new kind of stadium canopy which is a cable-stayed combined structure made of concrete filled steel tube space trusses and long-span arched steel.Based on nonlinear characteristics of the structure and its coupling effect with the wind,the nonlinear wind vibration responses of the new structure under the action of random wind load in time domain using the method of simulating the random wind loads are studied.
