摘要
销接钢梁体系的销孔间隙会使结构产生初始的几何位移 ,从而使结构在受弯的同时产生扭转 ,以致承载力降低。本文给出了销接钢梁考虑弯扭组合强度的一种近似计算方法 ,并以六四式梁拼组简支梁为例 。
The interstice between pin and pinhole in pin-connected steel beam system may generate the initial geometric displacement, thereby the structure generates torsion while bearing bend, which reduces carrying capacity. An approximate calculation method considering bend and torsion combination strength of pin-connected steel beam is introduced in this paper, Taking“64 type beam” assembled simple support beam as an example, the relational curve of carrying capacity and span is given.
