摘要
刚节点是倒L型桥墩结构受力的关键部位,但现行规范尚无刚节点构造细节和计算方法的详细规定。文章通过对倒L型钢筋混凝土桥墩刚节点结构的受力理论分析、刚节点开裂数值模拟、裂缝处理方案等多方面进行研究,提出倒L型钢筋混凝土桥墩刚节点结构优化设计建议。
With many studies including the theoretical analysis on the load-bearing by stiffness structure node of inverted L-shaped reinforced concrete pier, simulation of stiffness node cracking, solutions for crack treatment, the paper puts forward some recommendations on the optimization design of stift＇ness node structure for inverted L-shaped reinforced concrete pier.
