Abstract

The invention discloses a steel structure reinforcing joint part with multiple anti-seismic progressive-collapse-resisting defensive lines. The steel structure reinforcing joint part comprises a steelbeam, a steel column, a steel groove and truss chord members. The end of the steel beam is fixed to the steel column, the steel groove is fixed to the lower surface of a bottom flange of the steel beam, the side face of the steel column is provided with hinge supports, friction sliding blocks are arranged in the steel groove, through holes are formed in the bottom face of the steel groove, one ends of the truss chord members penetrate through the through holes to be connected with the friction sliding blocks, and the other ends of the truss chord members are connected with the hinge supports.According to the part, the problem that a traditional steel structure joint is poor in anti-seismic progressive-collapse-resisting capacity, and the structure is in brittle failure can be effectivelysolved.

Description

technical field [0001] The invention belongs to the field of steel structures and relates to a steel structure reinforced node component with multiple anti-seismic and anti-continuous collapse defense lines. Background technique [0002] Steel structure engineering is widely used in the construction industry due to its light weight, high strength, good plasticity and toughness, and a high degree of mechanization in manufacturing and installation. As the probability of building structures being subjected to accidental loads (such as earthquakes, fires, explosions, impacts, etc.) continues to increase during use, the probability of structural component damage or failure also increases significantly, which may cause local damage to the structure or even disproportionate occurrence. continuous collapse. After a certain component of the structure fails, the internal force will be redistributed inside the structure. Therefore, the joints have sufficient strength to ensure that th...
