梭形轻型钢屋架腹杆稳定计算中若干问题的探讨

Reseach on Subjects of Stability Analysis of Diagonal in Steel Light Roof Trusses with Shuttle Shape

探讨了腹杆带有矩形箍的梭形轻型钢屋架受压腹杆平面内和平面外失稳形态、腹杆稳定性计算长度、连接受拉与受压腹杆的矩形箍的作用及其对稳定性的影响。并提出了应用这种钢屋架的建议。

This artical inquires into the buckling shape and effective buckling length both in and out of plane for a compression diagonal with rectangle hoop in the steel light roof trusses which are shuttle in shape. The artical also probes into functions of the hoop connecting a tension and a compression diagonal, and influences as well on the stability. In addition, the artical offers proposals for using this type of roof trusses and points out some questions and views for some design methods which are not perfect.
