tension chord

The tension chord of trusses has the duty of providing lateral support to the connected compressive web members,so that its slenderness ratio should satisfy necessary requirement and relevant provision in design code has to be amended.

桁架受拉弦杆承担对受压腹杆的端部提供侧向支承的任务,其长细比应满足必要的要求,设计规范中的有关规定需要加以修改。

There were little data on the buckling behaviors of truss compression chord with some panels and non-hinge joints before.

本文从桁架上弦杆的稳定相关入手,同时考虑节点刚度的影响,以结构优化设计为目的,对桁架的受力性能进行了较全面的深入的研究、探讨。

In some truss structures,such as the roof truss undergoing heavy upward wind load,or the truss on both sides of a footbridge connecting different buildings,the service conditions do not allow us to place lateral support for the compressive chord members.

在一些受较大向上风载的屋架或连接不同单体建筑步行桥的两侧桁架等结构中,由于受到使用条件限制而无法为受压弦杆设置平面外的支撑系统,因此这些结构中受压弦杆在平面外的稳定问题就显得格外突出。

The calculation for the effective length of the compress ive chord members in the truss can not be considered as hinged joints or fixed i n each member end,because the compressive chord members of the truss are restra ined by the contiguous ones.

桁架受压弦杆受到相邻杆件的约束,其计算长度不能直接按两端铰接或两端固定杆件来取值。

The crack eventually caused the chord to fracture.

裂纹最终致使弦杆断裂。
