在计算多梁式桥梁横向分布系数刚接梁法的基础上,提出适用于多室宽箱梁空间实用计算方法的修正刚接梁法。将箱梁沿腹板间的顶底板切开成各片工字梁组成的桥跨结构,切口处以赘余力代替,建立力法方程组,编写赘余力求解程序,通过求解矩阵方程即可得出所有赘余力。并结合有限元实体单元模型,验证本文所推导的修正刚接梁法,讨论了其适用性和精确性。 Based on the calculation of the rigid beam method with transverse distribution coefficient of multi-girder bridge, a modified rigid beam method is proposed to be applied to the practical calculation of multi-chamber wide-beam box girders. The box girder along the top and bottom of the plate cut into pieces of the beam bridge composed of beam structure, the incision to replace the surplus power, the establishment of force law equations, the preparation of redundant solution to solve the program, by solving the matrix equation can be drawn All redundant. Combined with the finite element model, the modified beam-on method is validated and its applicability and accuracy are discussed.
