摘要
设计了一种用于节段拼装桥墩的弯曲螺栓连接构造,采用数值模拟方法对带连接桥墩和常规桥墩进行对比分析,结果表明:与常规桥墩相比,拼装桥墩初始刚度和破坏形态不变,极限侧向力承载能力下降很少,设计方案可行。
A kind of connecting using curved bolt for modular pier is designed in this paper. By using numerical simulation methods the performance of modular pier and conventional pier is compared. The results showed that: compared with the conventional pier,initial stiffness and failure pattern of modular pier is unchanged,lateral force resistance decreased only a little. The design is feasible.
