《建筑及其他结构风洞试验标准》(ASCE/SEI 49-21, Wind Tunnel Testing for Buildings and Other Structures)pdf下载

该规范主要为建筑和其他结构的风洞试验提供统一的技术要求和实施流程,用于确定结构在风作用下的设计荷载,包括主体结构、围护构件以及附属设施的风荷载取值。其结果可直接用于符合 ASCE 7 系列荷载规范的工程设计,是风洞试验在建筑抗风设计中应用的权威依据。

规范内容包括风场模拟要求(如大气边界层、地貌类别、湍流特性)、试验模型制作与安装标准、风荷载测量方法、数据处理与结果分析流程,以及试验报告的编制要求。通过标准化风洞试验,可更准确地评估高层建筑、大跨屋盖、高耸结构、幕墙系统等在强风作用下的受力与响应,为结构安全、经济设计提供可靠依据。

该规范适用于各类新建与既有建筑及特殊结构,尤其对风环境复杂或外形不规则的建筑具有重要指导意义,可有效提升结构抗风性能与设计效率。
