连栋温室结构设计中风荷载取值方法初探

A Preliminary Study on Calculating of Wind Load for Multi-span Greenhouse Structural Design

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风荷载的定义、计算取值等问题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,按中国建筑结构荷载规范(GB50009-2001)计算风荷载是相对保守的,但考虑风压高度变化系数、阵风作用因子和风荷载体型系数,按中国建筑结构荷载规范(GBJ9-87)计算风荷载是可行的,可不必进行重现期修正。

Based on the contrast analysis of loads provided in foreign and chinese standards,Analysis and discussion are mentioned about the definition and estimation of wind loads 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 relative safety in calculation wind load according to chinese architectural structure load standards(GB50009- 2001),Yet it is unnecessary for modifying the statistical factor in calculation wind load when considering the ground category height and structure size factor and the gust factor according to chinese architectural structure load standards(GBJ9-87)。
