Artificial plastic hinges have been widely used in the seismic research of frame structures, which can control the location of the beam plastic hinges and avoid the continuous collapse of the frame structure due to the damage of beam-column joints in earthquakes. The design goal of “strong column weak beam” can be achieved. An artificial plastic hinge with kinked rebar provides a new idea for structural blast resistance. Established structural static load tests have shown that the kinked rebar has excellent deformation performance. The ultimate load capacity of beam with kinded rebar is not reduced. With the software ANSYS/LS-DYNA and the hybrid finite element modeling approach, a numerical simulation study of reinforced concrete frame structures with different kinked rebar schemes was carried out. The results showed that the beam with kinked rebar can absorb the impact energy, reduce the support reaction, delay the peak reaction force, protect the beam-column joints, limit the damage to beam-slab members, and prevent the continuous collapse of frame structre.
