很多国家的风荷载规范,包括我国的荷载规范(TJ9-74),其中风振计算都采用了按单自由度体系导出的风振系数公式,这与实际情况不符.修订后的荷载规范按无限或有限多自由度体系重新导出新的简化公式,并采用表格形式,对高耸结构和高层建筑分别给出各项计算系数值。本文解释了有关的修订内容。 The wind load specifications of many countries, including our country’s load specifications (TJ9-74), wind-induced vibration calculations have adopted the wind-induced vibration coefficient formula derived from the single-degree-of-freedom system, which is inconsistent with the actual situation. The revised load specification is based on infinity. Or the limited multi-degree of freedom system re-exports the new simplified formula and uses a tabular form to give each calculation coefficient value for the towering structure and the high-rise building. This article explains the relevant amendments.
