摘要:
为避免中国现行《建筑结构荷载规范》(GB 50009—2001)中所采用的风振系数仅考虑结构的1阶振型,而不考虑周围环境影响对体型不规则超高层建筑结构抗风设计造成的不合理性,采用风洞试验与风振动力响应计算分析相结合的方法,考虑结构不规则的影响以及相邻建筑的气动干扰和横风效应来获得超高层建筑结构抗风设计所需的顺风向和横风向的等效静风荷载和风致动力响应。结果表明:由于周围建筑的干扰,顺风向、横风向的风荷载规律与一般超高层建筑不同,其不利角度也与规范存在差异; 所得结论为超高层建筑结构的抗风设计提供了依据和参考。
Abstract:
The wind vibration factor in current Load Code for Design of Building Structures(GB 50009—2001)in China was advanced only considering the first vibration shape of the structure, but for super high-rise building structures with complex shape, the above calculation method was incompletely reasonable. Considering the influence of irregular structure, aerodynamic interference of adjacent buildings and cross-wind effect, authors obtained the along-wind and cross-wind equivalent static wind loads and wind-induced dynamic response needed for wind resistant design of super high-rise building structures by using the method of combining wind tunnel test with wind vibration response calculation, and achieved good effects in project practices. The results show that because of interference of surrounding buildings, along-wind and cross-wind equivalent static wind loads differ from normal super high-rise buildings and the disadvantageous wind directions are inconsistent from those shown incode. The conclusions also provide evidence and reference for wind resistant design of super high-rise building structures.
