Double-coupling-beam structure with buckling restrained braces and construction method of double-coupling-beam structure

Abstract

The invention provides a double-coupling-beam structure with buckling restrained braces and a construction method of the double-coupling-beam structure. The double-coupling-beam structure comprises adouble-coupling-beam body and the buckling restrained braces; the double-coupling-beam body comprises a first coupling beam and a second coupling beam which are parallel to each other and are arrangedup and down in a spaced mode; and the buckling restrained braces are arranged between the first coupling beam and the second coupling beam, one ends of the buckling restrained braces are fixedly connected with the first coupling beam, and the other ends of the buckling restrained braces are fixedly connected with the second coupling beam. The buckling restrained braces are arranged in the double-coupling-beam body, the buckling restrained braces have the characteristic of separating the bearing capacity from the stiffness of the buckling restrained braces, thus the bearing capacity of the double-coupling-beam structure is effectively improved on the premise that the structural stiffness of the structure is not increased, and the buckling restrained braces can yield earlier than the double-coupling-beam body under the action of a large earthquake so as to play a role of a safety fuse, the double-coupling-beam body is prevented from yielding or being seriously damaged, the earthquake-proof capacity is good, the earthquake-proof property of the double-coupling-beam structure is effectively improved, and post-earthquake repair is facilitated.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a double-connected beam structure with buckling restraint supports and a construction method thereof. Background technique [0002] The earthquake recoverable function can prevent the basic functions of the building structure from being lost during minor earthquakes, and the basic functions can be restored in time after major earthquakes, so as to resist disasters during earthquakes and recover quickly after earthquakes, greatly improving disaster relief efficiency and reducing earthquake damage losses In high-rise buildings, the reinforced concrete shear wall is an important anti-lateral component; the connecting beam is used to connect the two sides of the wall, as the first anti-seismic defense line in the shear wall structure, which plays an important role in the anti-seismic performance of the entire building structure. It plays a vital role; the coup...
