Abstract

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.
