摘　　要：本文给出了钢网架和钢网壳结构中轴心受压杆件、拉弯和压弯杆件截面设计的简捷方法，与通常采用的逐次逼近法相比，可避免反复试算，大大减少计算工作量，提高设计效率。在工程实际中应用该方法。In this paper, a simple and direct method for design of the cross section of the axially loaded compression members and members subjected to combined axial load and bending in steel space truss and reticulated shell structures is given. The method takes much less time than the trial and error method usually used before, and it is very simple. Four illustrative examples are worked out in the paper.
