本文采用变形法,对四边简支等刚度常用斜向井字网格梁内力及挠度作了推导,并列表供设计者在个体设计中当遇到较狭长的矩形房间楼面,屋面在采用斜向网格梁布置时直接选用。
In this paper, the deformation method is used to deduce the internal forces and deflections of commonly used oblique-head grid beams with simple stiffness and stiffness, and the list is for designers to encounter narrow and long rectangular room floors in individual design. The roof is inclined. Grid beams are directly selected when they are arranged.
