TEST STUDY ON WIND PRESSURE DISTRIBUTION ON WIND-BREAK WALL OF SUPPORT STRUCTURE SYSTEM OF AIR COOLED CONDENSER
-
摘要: 空冷凝汽器支架结构是一种新型的工业建筑，该类结构抗风设计时有许多参数不很清楚，而我国现行荷载规范给定的风参数不能直接采用。结合空冷支架结构的特点，制作了1∶150的刚性模型，进行了风洞试验研究。详细介绍了空冷支架结构上部挡风墙表面平均风压的风洞试验结果及风洞试验数据处理方法，探讨了挡风墙风压分布规律的几个重要影响因素，所得结论对该类结构抗风设计有重要的指导意义。Abstract: Support structure system of air cooled condenser is a new industrial construction,whose wind load parameters are not very clear and the proposed wind parameter in present load code can't be directly used.According to the character of this kind of structure,a rigid model with 1∶150 scaling factor was made, and the wind tunnel test about mean wind pressure on wind-break wall surface was carried out.In this paper,wind tunnel test for wind pressure distribution on wind-break wall surface and test data processing were presented in detail.Moreover,several important attributes to wind pressure distribution were discussed.Conclusions given by this paper have important guiding meanings for the wind resistance design of this kind of structure.
