摘　　要：温室天沟是温室结构的重要受力构件,天沟的抗弯承载力和稳定性主要取决于天沟的抗弯刚度。对温室工程中常用的5种天沟截面形式的特性参数进行对比研究,分析各截面变量对特性参数的影响,并优选出抗弯刚度最大的天沟截面形式。Gutter is the essential load bearing member in the greenhouse structure,and its bending capacity and stability mainly depend on its bending stiffness.In this paper,the characteristic parameters of five types of cross section commonly used in gutter were studied,and the influence of different cross-sectional variables on characteristic parameters was analyzed,and finally the cross section which has the highest bending stiffness was selected.
