| 摘 要： | 本文提出了采用极值分布变换法统计最大平均风速的建议,给出了结构风振的计算方法,首次导出了Davenport风速谱所对应的结构风振反应统计量的解析式。文中求得了风振动力系数的精确解,并与荷载规范中的近似解进行了比较,指出了其误差和问题。最后在考虑了随机抗力的基础上,提出结构抗风可靠性的分析方法。

| Abstract: | This paper proposes a suggestion about statistics of maxium mean wind speed by use of the translation method of extrem distribution based on the closed solution of structural response corresponding to Davenport spectral, a calculation method of structural response under wind load is given. The precise solution of dynamic coefficient wind vibration is obtained and compared with the solution and appoximate solution given in load code of China. The paper also points out the problems in load code of China. Finally, on the base of considering the randomness of resistant force the paper puts forward the method of reliability analysis of structures under wind load. |
