Different cross-section types require different connection types. The shear-type energy-dissipating beam section can use I-shaped section and double-channel steel section. As for the energy-dissipating beam section with double-channel steel section, there is currently no one that can be used for double-channel steel section. Replaceable connection type between energy-dissipating beam section and non-energy-dissipating beam section with channel steel section

Embodiment Construction
[0036] The present invention will be further described below in conjunction with accompanying drawing.
[0037] see figure 1 , the present invention arranges an easily replaceable double-channel steel section energy-dissipating beam section 2 in the middle of the steel skirt beam 1 of the peripheral frame of the traditional steel frame tube structure, and is mainly used for the steel skirt beam and the replaceable double-channel steel shearing type energy-dissipating beam section between the connections.
[0038] see Figure 2 to Figure 5 , the double-channel steel section can replace the energy-dissipating beam section-steel skirt beam connection structure, including two steel skirt beams 1 welded to the outer frame column 8 of the steel frame tube, the two steel skirt beams 1 are arranged opposite to each other, and the two steel skirt beams 1 The webs of the skirt beam 1 are respectively connected to the two ends of the energy dissipation beam section 2, the webs of the t...

The invention discloses a replaceable energy dissipation beam segment-steel skirt beam connecting structure with a double-steel channel section and an installing method. Replaceable energy dissipationbeam segment is arranged in a steel skirt beam span of a traditional steel frame tube structure and connected with steel skirt beams, according to the connecting form, first bolts of an eccentric shearing bolt group are used for transmitting shearing force and bending moment, and force transmission is simple and reliable; after an earthquake, it is only needed to disassemble the first bolts, thedamaged energy dissipation beam segment is removed, a new energy dissipation beam segment is installed through the first bolts and then can be replaced, the using function of the structure is restoredrapidly, operation is simple and rapid, on-site construction is rapid in operation, repairing costs are low, and good economic benefits are high. The replaceable energy dissipation beam segment-steelskirt beam connecting structure is provided with skirt beam reinforcing plates and energy dissipation beam segment reinforcing plates, and it can be prevented that the walls of bolt holes deform excessively under borne pressure.
Description
technical field [0001] The invention belongs to the field of construction engineering and structure anti-seismic, in particular to a double-channel steel section replaceable energy-dissipating beam section-steel skirt beam connection structure and an installation method. Background technique [0002] With the development of our country's economy and the progress of construction technology, high-rise buildings have become the main building types of modern urban construction. The steel frame tube structure has the advantages of high lateral rigidity, good torsional performance, and flexible structural layout. It is a lateral force resistant structural system with excellent performance. The traditional steel frame tube structure has a small outer frame tube column spacing and a high skirt beam section, which does not conform to the design concept of strong columns and weak beams. Under earthquake action, plastic hinges often appear at the end of the column before the end of th...
