铰接简支梁、板桥的计算,目前仍用苏联理论,该法忽略扭曲挠度的影响。为此,本文作者从结构试验受力变形的规律出发,考虑了端横梁的抗扭作用、外载是集中载重及桥跨纵向铰接缝传递竖向剪力的特点。用能量法原理,导出单片梁的挠度方程,再利用变形协调原理,推导了荷载横向分布系数的计算公式,另外在此基础上验证了本文的精度和探讨了无中横隔梁桥的合理性。它适用板、有或无中横隔梁、无横隔梁桥设计。
The calculation of hinged simply supported beams and slabs is still based on the Soviet theory, which ignores the effect of torsional deflection. Therefore, the author starts from the rule of structural deformation and considers the torsional resistance of the end beam. The external load is the characteristic of concentrated load and vertical shear force transmitted through the longitudinal joint of the bridge span. Based on the energy method principle, the deflection equation of the monolithic beam is deduced, and then the deformation coordination principle is used to derive the formula for calculating the transverse distribution coefficient of the load. In addition, the accuracy of this paper is verified and the reasonable Sex. It applies plate, with or without the diaphragm, without the diaphragm bridge design.
