 abstract={The continuation of a multistage research project based on experimental and numerical analysis is presented, focused on the robustness of the steel frame structure with bolted end-plate joints. An advanced FE model, validated on previously performed experimental tests of steel bolted joints and steel subframe structure, was used. A dynamic numerical analysis of planar steel structures was performed under a sudden internal column loss scenario using Abaqus software. An attempt was made to increase structural robustness in the event of a sudden removal of the internal column at the ground level of the steel frame with flush bolted end-plate joints. The application of a strategy based on the change of types of joints at the selected level of the structure was shown. Two main structural changes were implemented by using bolted extended end-plate joints, instead of flush end-plate, or by using the novel joint with additional rings. To check the behaviour of the structure and assess its robustness, a change of the joints was applied at the lower and upper levels of the structure. The use of bolted extended end-plate joints only in one level of the structure leads to progressive collapse of part of the structure. The application of the novel joint with additional double rings at one level of the frame in both analyses leads to obtain a required level of robustness and mitigates collapse of the structure.},
