基于风洞试验实现高耸结构抖振时域分析的两种方法

Two Approaches Applied in Buffeting Analysis of High-rise Structure in Time Domain Based on Wind Tunnel Test

随着高耸结构的日益高大和轻柔化,由紊流风引起的结构抖振响应问题显得格外重要。通过静力三分力试验及气动弹性模型试验两种不同的途径分别实现高耸结构时域内的抖振分析,并以算例分析证明两种方法的可靠性,明确不同途径工作的难点所在,有利于设计者更好地选用合适的分析途径。

With the height increasing of high-rise buildings, the buffeting response becomes more flexible and more intensive. How to carry out buffeting analysis in time domain based on aerostatic force testing and aero elastic model testing is presented, whose reliability were demonstrated by examples. In order to provide definite information for designer to select an appropriate approach, the difficulties to be facing by different approaches were discussed.
