摘要
首先,对中、澳、欧风荷载规范中影响平均风荷载和脉动风荷载的主要参数进行了对比研究。然后,基于随机振动理论,通过算例对不同风速谱和不同相干函数下的脉动风响应进行了计算分析。最后,按照中澳欧三种风荷载规范分别计算了柔性结构和刚性结构的荷载和响应,并进行了比较分析。
First, the contrastive research was conducted on the main parameters which affect the mean wind load and fluctuating wind load in the codes of China, Australia and Europe. Then, based on the random vibration the- ory, the response induced by fluctuating wind under different wind spectrums and different coherence functions were calculated and analyzed. Finally, according to the three wind load codes, the load and response of a flexible structure and a rigid structure were calculated respectively, and the comparative analysis was carried out.
