| 摘 要： | 对高层钢框架－支撑结构二阶随机风振响应进行了分析。对钢支撑引进了三元件模型，形成了考虑二阶效应的结构刚度矩阵。在脉动风荷载的随机模型基础上推导了结构顺风向的随机反应公式，并结合工程算例，探讨了二阶效应对结构风振响应统计量的影响。

| Abstract: | In this paper, analyses of second_order random wind vibration response for steel braced frame structures in highrise buildings are carried out. A type of three element model of steel braced is proposed, then a second_order stiffness matrix is formed. Based on random model of dynamic wind force, the formulas of random response of structure in along wind direction are derived. In the illustrative examples, the second_order effects on the statistic values of the structural wind vibration response are discussed. |
