| 摘 要： | 在分析比较国外关于温室建筑及我国工业与民用建筑结构荷载规范的基础上,针对温室结构设计中动态风压的定义方法、计算取值等进行了较深入的探讨;同时结合工程实践,提出了一套适合我国温室结构设计中风荷载取值的一般原则:在现有条件下,考虑风压高度变化系数和阵风作用因子,按中国建筑结构荷载规范(GBJ9-87)计算风荷载-动压是可行的,可不必进行重现期修正

| Abstract: | Based on the contrast analysis of loads provided in foreign and Chinese standards, analysis and discussion are mentioned about the definition and estimation of dynamic wind pressures for multi span greenhouse structural design in details. Meanwhile, taking advantage of past experience in greenhouse structural design a practical method which can be used in greenhouse design was given for wind load. Under the present conditions, it is unnecessary to make modification of statistical reappearing factor in calculation wind load dynamic pressure when considering the coefficients of wind pressure depending on height and the gust factor according to Chinese architectural structure load standards(GBJ9-87). |
