- Non-steel-cell joint section is a common way to connect the steel beam and the concrete beam in steel-concrete hybrid girder bridge, and the PBL connector with large rigidity is usually adopted in non-steel-cell joint section. Shear resistance of PBL connector determines the success of joint force transmission. But the PBL connection in different structures has different boundary conditions and the state of stress. By means of the finite element numerical analysis method, the different failure modes of the steel roof and the bottom plate PBL connector under ultimate bearing capacity load were analyzed. The results show that the concrete stress level of compressive zone of columns hole is relatively balanced; the stress value of concrete in tensile stress area of connector close to bearing plate hole is bigger, and the stress value of concrete far from bearing plate hole is low. When PBL connector is in compression zone, it will make full use of its shear capacity to a greater degree.
