Corrugated steel web beam combined joint structure and assembly method

Abstract

The invention discloses a corrugated steel web beam combined joint structure and an assembly method. One end of a transition connecting beam is fixedly connected with the side wall of a box column, and the other end of the transition connecting beam is fixedly connected with one end of a corrugated web steel beam through a buckling restraining plate; a concrete plate is fixedly connected with the upper ends of the transition connecting beam and the corrugated web steel beam through shear-resistant studs, and the concrete plate is poured on the upper ends of the transition connecting beam and the corrugated web steel beam; and the transition connecting beam and the corrugated web steel beam are spliced, the concrete plate is arranged on the upper ends of the transition connecting beam and the corrugated web steel beam, the connecting position of the transition connecting beam and the corrugated web steel beam is not yielded under the design bending moment effect, under the earthquake effect, the connecting part of the transition connecting beam and the corrugated web steel beam yields before a main steel frame, and the connecting position of the transition connecting beam and the corrugated web steel beam is damaged in a concentrated mode through high ductility and high energy dissipation capacity of low-yield-point steel, so that the purpose of protecting the main structure is achieved, and rapid recovery is achieved by replacing the connecting part after an earthquake.

Description

technical field [0001] The invention belongs to the field of steel structure construction engineering, and in particular relates to a corrugated steel web beam combined node structure and an assembling method. Background technique [0002] With the development of urban construction, more and more high-rise buildings and fast buildings have become the main structure of urban buildings. In the building structure, reinforced concrete beams, as the main force-bearing components, play an important role in bearing and transmitting loads. Reinforcement is required for seismically damaged structures that can continue to be used after an earthquake, or some building structures whose functions have changed. On the other hand, most reinforced concrete beams are in the working state with cracks. In the atmospheric environment, especially in the corrosive environment, with the passage of time, the steel bars in the beam will corrode, resulting in a decrease in bearing capacity. It needs...

Problems solved by technology

Some components of the traditional steel structure system are widely used in welded rigid connections in actual engineering. Since the peak stress of the welded beam flange welds is at the start and arc extinguishing of the welds, it is more likely to cause fracture and tear at the welds, resulting in connection failures. The plastic rotation capacity of traditional steel frame joints is poor, and the beam-column connection welds of traditional steel frame nodes are easy to be damaged, and it is difficult to achieve post-earthquake repairs
