无中横隔梁桥是由多根主梁及端横隔梁组成。它经各地推广,现已成为我国常用桥型结构之一。它的计算方法:目前仍套用苏联Б·Е·уличкий理论,不计端横隔梁的是集中载重及横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,然后利用变形协调原理,又推出荷载横向分布的计算公式;再在此基础上探讨了端横隔梁的作用。
None of the cross-beam bridge is composed of multiple beams and end beams. It has been popularized all over the country, and now it has become one of the common bridge structures in our country. Its calculation method: At present, the theory of the Soviet Union Б Е уличкий is still applied. The characteristics of the end load-beam and the vertical shear force of the transverse joint joint are not counted. Based on the energy law, the deflection equation of the monolithic beam is deduced. Based on the principle of deformation coordination, the formulas for calculating the transverse distribution of load are deduced. Based on the above analysis, the function of the end diaphragm is discussed.
