摘要
通过风洞试验对椭圆截面高耸结构的风荷载特性及结构抗风安全性进行了系统研究。获得了结构表面风压分布规律,研究了高耸结构三维风荷载功率谱特性,评估了结构的三维等效静力风荷载并和规范结果开展了对比性研究,讨论了结构抗风动力可靠性。研究结果可为高耸结构的抗风设计和风洞试验提供技术参考。
The characteristic of wind loads on and wind-resistant safety of an oval-shaped high-rise structure were evaluated by a wind tunnel test.This paper presents some selected results of the distributions of wind-induced pressure on the structure based on the analysis of the data obtained in the wind tunnel test.The spectral characteristics of along-wind,across-wind and torsional components were studied in detail.In addition,the equivalent static wind loads were calculated based on the wind tunnel results and compared with those estimated from the building design codes of China.The wind-resistant safety of the high-rise structure was also investigated.The outcomes of this study are expected to provide guidelines for the design and wind tunnel tests for other similar structures in the future.
