提出了基于性能的钢筋混凝土梁柱节点拉压杆模型优化方法。采用基于性能的优化方法（PBO）对钢筋混凝土梁柱节点拉压杆模型进行了优化研究。钢筋混凝土梁柱节点拉压杆模型的建立被视为一个拓扑优化问题。在优化过程中，通过逐步去除节点中的无效有限元，生成混凝土梁柱节点的最优拉压杆模型。提出了开口节点、梁柱外节点和梁柱内节点的拉压杆优化设计模型。
This paper presents the performance-based optimization of strut-and-tie models in reinforced concrete beam-column connections. The performance-based optimization (PBO) technique is employed to investigate optimal strut-and-tie models in reinforced concrete beam-column connections. Developing strut-and-tie models in reinforced concrete beam-column connections is treated as a topology optimization problem. The optimal strut-and-tie model in a concrete beam-column connection is generated by gradually removing inefficient finite elements from the connection in an optimization process. Optimal strut-and-tie models for the design and detailing of opening knee joints, exterior beam-column connections and interior beam-column connections are presented.
