摘要
结合重庆某高层建筑,将建筑等效成二维离散模型,采用Davenport风速谱模拟作用在建筑物上的风荷载。分别采用星谷胜和Shinozuka对于风荷载模拟的理论,模拟出脉动风荷载时程曲线,并对两种理论模拟结果进行比较。
The high rise building in Chongqing in this article is simplified as a two-dimensional lumped mass model, and the Davenport wind spectrum is adopted to simulate the wind load on the building. Different theories are also used to simulate the fluctuation wind load, and the results of the simulations by different theories are compared.
