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.
本发明提供了一种具有屈曲约束支撑的双连梁结构及其施工方法，包括双连梁本体及屈曲约束支撑；双连梁本体包括第一连梁和第二连梁，第一连梁和第二连梁相互平行，且上下间隔设置；屈曲约束支撑设置在第一连梁与第二连梁之间，屈曲约束支撑的一端与第一连梁固定连接，另一端与第二连梁固定连接；本发明通过在双连梁本体中设置屈曲约束支撑，屈曲约束支撑具有将自身承载力和刚度分离的特点，实现在不增加结构刚度的前提下，有效提高了双连梁结构的承载力，在大震作用下，屈曲约束支撑能够先于双连梁本体发生屈服，起到保险丝的作用，避免了双连梁本体发生屈服或严重破坏，具有良好的抗震能力，有效提高了双连梁结构的抗震性能，便于震后修复。
