风荷载作用下建筑结构表面的压力分布研究

Research on the Pressure Distribution of Structure under the Wind Load

针对浙江沿海地区台风对高大柔性结构损坏严重的现实,利用数值风洞技术,研究顺风向情况下柔性结构静动力风荷载和位移方程和横风向情况下结构风振方程,运用有限元软件分析结构在流场中的应力分布.数值分析结果与风洞实验对比显示选取得模型合理可行,计算结果对改进结构设计、提高结构抗风性具有指导作用.

In Zhejiang coastal areas,the lofty flexibility structure are damaged reality specifically.The numerical wind-tunnel technology is used.The finite element software is applied on the research on structure pressure distribution.The contrast between air tunnel experiment and numerical wind-tunnel displays the model reasonable.The numerical result improves the structure design and the wind resisting.
