ABSTRACT
In recent years, with the continuous development and wide application of high-strength steel in the field of construction, the research on the performance optimization of beam-column joints in high-strength steel structures has become increasingly important. This study aims to investigate the hysteretic performance of high-strength steel single-ribbed reinforced beam-column joints. Based on high strength steel properties test and tensile test of welded joint plate, two reference groups are established: high-strength steel common beam-column joints and ordinary steel single-ribbed reinforced beam-column joints. Finite element models are developed for the three types of joints to analyze their stress patterns, failure modes, hysteretic curves, skeleton curves, ductility, ultimate bearing capacity, and energy dissipation capacity under low cyclic reciprocating loads. It is found that high-strength steel single-rib reinforced beam-column joints can enhance the deformation capacity and initial stiffness of the joints. They exhibit improved ductility and energy dissipation capacity, as well as increased joint stiffness and a slower rate of stiffness degradation. This study provides valuable data for the design methods of high-strength steel structure beam-column joints.
