Nonlinear Finite Element Analysis of a Composite Joint with a Blind Bolt and T-stub

A detailed nonlinear finite element model was established based on completed experiments to investigate the behavior of a blind-bolted T-stub composite joint that connects beam concrete-filled square tube column. This accomplished by comparing experimental results and simulation using hysteresis curve, failure mode, plastic deformation strain development ensure reliability accuracy model. parametric study carried out base expand library test data. It observed from comparison proposed FE predicted joint. The wall thickness column reinforcement ratio had significant influence ultimate bending moment performance mainly controlled when concrete slab under positive moment. flange T-stub, web axial compression little effect
