提出了一种新型的桥梁钢梁与钢筋混凝土桥墩的刚节点联结形式 .刚节点内部构件间的连接全部采用高强度螺栓连接方式且施工方便 ,能够较理想地将上部结构弯矩传递到下部结构 ,剪力传递钢板承受了大部分的水平剪力 .通过静荷载反复试验获得了有关这种新型结构性能方面的有效数据 ,试验结果表明该结构内部应力传递路径明确 ,并具有良好的抗震性能 .有关结构的强度和塑性变形的计算及试验结果均表明 ,这种结构即使在发生很大变形的情况下 ,也能保持良好的能量吸收功能且没有出现因应力集中而发生的局部曲屈现象 .由于避免使用了价格昂贵的支座 ,采用这种新型组合结构形式不但具有良好的抗震性能 ,同时可以降低桥梁的建设成本
A new type of just-connected form of bridge girder and reinforced concrete piers is proposed.The connection between the internal components of the rigid node is entirely made of high-strength bolts and the construction is convenient, which can transmit the moment of the superstructure to the lower structure , The shear transfer plate is subjected to most of the horizontal shear force, and the effective data on the performance of this new structure is obtained through repeated tests of static load. The experimental results show that the internal stress transfer path is clear and has good seismic performance. Calculations and experimental results on the strength and plastic deformation of the structure show that this structure maintains good energy absorption even in the case of large deformation and does not exhibit local buckling due to stress concentration. Due to the avoidance of costly bearings, the use of this new combination of structural forms not only has good seismic performance, while reducing bridge construction costs
