| Abstract | ||
| The beam-column connection approach significantly impacts the seismic performance of frame structures. This report proposes a novel resilient prefabricated hinged beam-column joint equipped with rotation control and energy-dissipating load-bearing capabilities (RCEL-RPHJ). The design facilitates off-site prefabrication and on-site assembly, encompassing a prefabricated column with cantilevered section, a prefabricated beam, and a hinged core area with rotation control. Initially, the paper details the configuration, assembly process, and working mechanism of the RCEL-RPHJ. Subsequently, a numerical simulation analysis of the RCEL-RPHJ is conducted following the validation of the finite element modeling strategy. And taking into account 10 different factors, a parametric analysis was performed on a total of 18 finite element models of the RCEL-RPHJ. Findings reveal that the secondary peak load of the RCEL-RPHJ exceeds initial peak load by 7%. After loading, plastic deformation is concentrated in the cover plates, lateral plates, and limiting bolts of the hinged core area, with no significant inelastic deformation in other main components. For optimal rotational control and energy dissipation, the specification of limiting bolts should be M20 or larger, and in configurations with a cantilever, the distance between the hinge core and the column end should be less than 545 mm. | ||
