摘要
Abstract
To investigate the behavior of bolted end-plate connections to concrete-filled steel tubular(CFST)columns utilizing a novel slip-critical blind bolt(SCBB),finite element(FE)models were developed using ABAQUS.Model parameters were calibrated based on existing joint experiments.The FE models were validated against test results through comparisons of failure modes,hysteretic curves,ultimate bearing capacity,elastic stiffness,and energy dissipation capacity.Furthermore,parametric analysis examined the influence of the beam flange width-to-thickness ratio,reinforcement layout,and reinforcement ratio of the reinforced concrete(RC)slab on joint mechanical properties.Results indicate that beams complying with the S1 and S2 width-to-thickness ratio criteria are suitable for seismic energy dissipation.Variations in reinforcement layout and ratio exerted marginal effects on the ultimate bearing capacity and elastic stiffness of the joints.关键词
