开孔加强结构 opening reinforcement structure
本文采用刚性模型风洞试验研究开孔结构风致内压特性。
Wind tunnel tests of rigid structural model are carried out to investigate the internal pressure of structures with openings.
提出了估算开孔结构风致内压脉动的频域分析方法，并实施了风洞试验进行验证。
A method for estimating wind-induced fluctuating internal pressure in the frequency domain is proposed and wind tunnel tests were carried out to verify the method.
因此，研究开孔结构的风效应是一个重要课题，对进行大跨空间结构抗风设计具有十分重要的意义。
Therefore, it is a important issue to investigate the wind effect for large space roof structure with openings. And it is of great significance in wind resistance design.
