铰结板梁桥结构的分析计算通常采用横向分布系数的理论来确定每一根梁在荷载作用下分配到的荷载,然后把所分配到的荷载按影响线或影响面加载到所求解的梁上进行结构分析,该方法以手算为主,效率较低。提出基于梁格理论结合SAP2000,利用铰结板梁传递剪力不传递弯矩的结构特点,对整体简支板梁桥进行空间梁格体系模拟分析,并且通过实例计算,结果表明该计算方法简便,直接可得结构计算内力,具有很高的工程使用价值。
The analysis and calculation of the bridge girder bridge structure usually use the theory of transverse distribution coefficient to determine the load that each beam distributes under the load and then load the assigned load to the solved beam according to the influence line or influence surface On the structural analysis, the method is mainly manual, less efficient. Based on the theory of beam lattice combined with SAP2000, the structural characteristics of the shear-stress non-transmitting moment of the hinge-slab beam were analyzed. The simulation analysis of the beam-to-beam system was carried out. The calculation results show that the method is simple , Directly available structure calculation of internal forces, with high value of the project.
