因结构具有整体受力性能,外荷载并不直接作用在横向联接构件上,也不是平均分配到各个横向联接构件上的。本文对荷载的这一纵向分配问题,拟按弹性支承梁法进行求解,不妥之处,恳望指正。一、基本假设在参与结构的整体受力时,伴随主梁(拱或刚架、桁架等——以下略)挠曲而产生竖向位移的横向联接构件可视为主梁的弹性支承,主梁的弹性支承反力与外荷载经由主梁传递到横向联接构件上的作用力等值异号。因而,只要主梁的弹性支承反力一旦求出,分配在横向联接构件上的荷载以及横向联接构件的内力计算问题也就迎刃而解(当
Because the structure has the overall force performance, the external load does not directly act on the transverse coupling member, nor is it evenly distributed to each lateral coupling member. In this paper, the problem of longitudinal distribution of loads is to be solved according to elastic beam method. First, the basic assumption in the overall structure of the force, along with the main beam (arch or frame, truss, etc. - the following abbreviation) vertical displacement of the lateral coupling member can be regarded as the main beam of the elastic support, the main The elastic support reaction force of the beam is different from the force equivalent value of the external load transmitted to the transverse connection member via the main beam. Therefore, once the elastic supporting reaction force of the main girder is calculated once, the load distribution on the transverse coupling member and the calculation of the internal force of the transverse coupling member are easily solved
