摘要:
本文依据: (1) 由平面格构模型发展而来的平面板梁模型和原板理论; (2) 半波正弦荷载的等作用量原则; (3) 内力横向分配概念,提出了平面曲线形箱梁桥为基础的形箱梁桥内力横向分配计算方法,解决了它的最大活载内力计算问题,同时也大大简化了这种梁的恒载内力计算。本法可以代替弹性薄壁杆理论,作为直的或曲的、单箱或多箱或分离箱式箱形梁桥的基本设计工具。
Abstract:
The method is established on the following bases: 1. the plane plat-girder mechanical modal developed from the plane grillage and the thick-plat theory; 2. the principle of equal amount of action of half-wave sinusoidal load; 3. the principle of distribution of the internal forces. The method is able to greatly simplify the calculation of the maximum internal forces caused by live loads as well as dead loads and may be used as a basic one instead of the thin-walled beam theory for design of straight or curved, single-cell or multi-cell box-girder bridges.
