摘要
以工程实践中常用的 6m跨C1 60× 70× 2 0× 3卷边檩条为研究对象 ,在风吸力作用下 ,考虑檩条的支座连接条件、拉条刚度、拉条布置位置、屋面对檩条有无侧移约束作用等因素 ,采用ANSYS5 7通用程序进行了大量双重非线性分析 ,给出了各种荷载条件下的拉条内力、檩条的极限承载力和轴压 横向荷载线性相关表达式 。
The behavior of common thin walled channel purlin C160×70×20×3 (6m span) subjected to wind uplift load is studied.The factors such as support conditions,location and stiffness of the pulling rod,the lateral restraints offered by roof panels etc.,are taken into consideration.Based on the analyzing results by means of ANSYS5 7,the inner force of the pulling rod,ultimate load carrying capacity and the linear interaction equation between axial compression and lateral load of the purlin are obtained.And some practical design suggestions are also proposed.
