| 摘 要： | 风压是建筑设计中很重要的基本设计数据之一,特别是高耸构筑物,它是设计上主要控制荷载。因此,为了使建筑结构设计做到安全、经济和适用,正确地确定风压是非常重要的。由于各种建筑物寿命不同,要求的风压值也各异。木文根据各种建筑物的要求,按极值分布理论,计算了10、20、30、60和100年一遇的风压值,这些资料已列入有关部门的规范或手册中。

| Abstract: | In this article the regular teriminal observations of 2-munite average wind velocity are converted to 10-munite ones by formulae for different regions with different values of air density and gravitational constants.The equation of wind pressure coefficient q as a function of elevation (h) obtained is q=0.0644 e-0.0001h.Nationwide charts for return period of wind pressure once in 10,20,30,60,and 100 years have been prepared for the benefit of various fields of engineering.These charts have been included in the design codes for road,railway,electric power,telecommunication and harbour engineering. |
