摘要:

为了得到经济合理的抗风设计方案,提出一种基于Copula函数的高层建筑动力风荷载相关性组合方法.在某高层建筑模型高频动力天平试验(HFFB)数据的基础上,通过Copula函数和风荷载分量的边缘分布构建任意两分量的联合概率密度函数(JPDF),引入条件极值,计算二者的相关关系和组合值;利用各风向角下的组合值构建了最不利包络荷载组合,并以此为结构的设计风荷载.结果表明,该方法能够确定给定保证率下任意两风荷载分量的组合关系;以最不利包络荷载组合为设计风荷载能保证结构的抗风安全性.

Abstract:

Based on Copula functions a dynamic wind load combination method was developed to achieve more economical wind-resistance structural designs of tall buildings. The joint probability density functions (JPDF) of wind load components were constructed by making use of the wind tunnel data derived from the high frequency force balance (HFFB) test for a high-rise building. The correlations and combination effects of two wind load components were quantified with the condition that one of those reaches its maximum. The worst envelope of load combinations were also determined from the wind load combination results under all incident wind directions, and could be used as design wind loads. The design wind loads generated by the proposed method have a pre-assigned non-exceedance probability and could result in not only safe but more economical design for tall buildings against wind hazards.
