| 摘 要： | 高层建筑表面的风压大小及分布是结构设计风荷载的主要依据，其考虑的因素很多。本文应用国际通用的CAARC刚性模型进行测压试验，主要研究分析紊流条件与平滑流条件下的模型表面的风压分布规律，同时分析了这两种条件下体型系数随风向角的变化规律，其结果对结构的抗风设计有一定参考价值。

| Abstract: | The distribution regulation of wind load on the building is based of structural design ,which is effected by many factors. Based on the data of the CAARC model in wind tunnel test, the distribution regulation of pressure coefficient on the building, in turbulence and homogeneous environment, is introduced, and the both laws of the varying shape coefficient with attack angle have been discussed. The results given by the paper might be a significant guide for structural design. |
