| 摘 要： | 大量风洞试验研究表明,风压沿建筑物横向的变化非常明显,呈抛物线形状分布,而现行的GB50009-2001<建筑结构荷载规范>对风荷载平均风压取值的简化计算标准,并未考虑这一影响.在风洞试验的基础上,通过对试验数据的数值分析和拟合,得出了风压系数沿建筑物横向变化的简化计算公式.算例研究表明,风压沿建筑物表面位置的横向变化对规则巨型框架结构变形的影响较大,在设计中应予以考虑.

| Abstract: | The massive wind tunnel test research indicated that,the wind pressure is extremely obvious along the building crosswise change,assumes the parabola shape distribution,but present Load code for the design of building structures(GB50009-2001) windward load average wind pressure value simplification basis of calculation,considers this influence by no means.Base on the wind tunnel test foundation,and the tentative data numerical analysis and the fitting,has obtained the wind pressure coefficient along the buil... |
