Corrugated steel web beam steel frame beam column connecting joint and assembling method

Abstract

The invention discloses a corrugated steel web beam steel frame beam column connecting joint and an assembling method. A box-shaped column, a transition beam section and a connecting beam section structure are adopted, and a transition web of the transition beam section is vertically fixed between a transition upper flange and a transition lower flange plate; one end part of the transition web plate, one end part of the transition upper flange plate and one end part of the transition lower flange plate are fixedly connected with the outer wall of the box-shaped column, the end plate is fixed to one end of the connecting beam section, the transition web plate of the transition beam section is fixedly connected with the end plate through bolts, and the transition beam section and the connecting beam section are spliced to form a spliced installation structure connected through bolts. Under the design bending moment effect, the joint of the transition beam section and the connecting beam section does not yield, under the earthquake effect, the joint of the transition beam section and the connecting beam section yields before the main steel frame, the joint of the transition beam section and the connecting beam section is damaged in a concentrated mode through high ductility and high energy dissipation capacity of low-yield-point steel, the purpose of protecting the main structure is achieved, and after an earthquake, quick recovery of the structure function is realized by replacing a flange buckling restraining device.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a corrugated steel web beam steel frame beam-column connection node and an assembly method. Background technique [0002] With the development of urban construction, it is required that the buildings formed in urban construction can make the city itself resist disasters and recover quickly, so as to maintain the normal operation of urban functions and improve the city's risk prevention and control capabilities. In order to realize the goal of "seismic city with recoverable function", "seismic structure with recoverable function" after the earthquake is a key issue that needs to be solved urgently.

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 the traditional steel frame joint beam-column connection is easy to be damaged, and it is difficult to achieve post-earthquake repair
