A lead core tenon limiting damper system can not only prevent beam bodies from falling off longitudinally and transversely but also achieve vertical limiting of the beam bodies in an earthquake and meanwhile can achieve the effects of seismic reduction and energy dissipation. All assemblies are replaceable modular products so that the assemblies can be conveniently repaired and easily replaced after the earthquake. The lead core tenon limiting damper system comprises a steel tenon and a steel buckle. The steel tenon comprises a head, a buckle fixing section, a tapered section and an anchor plate from top to bottom, wherein a tapered cavity is formed in the tapered section, and a lead core is poured in the tapered cavity. The outer end of the steel buckle embraces the steel buckle fixing section, and a bottom plate is located at the inner end of the steel buckle. The steel tenon and the steel buckle are arranged on the outer side of padstone in the transverse direction of a bridge. The steel tenon is fixedly mounted on the top of a pier body through high-strength bolt assemblies penetrating through mounting holes in the anchor plate of the steel tenon, and the steel buckle is fixedly installed on the side wall of a beam body through high-strength bolt assemblies penetrating through mounting holes in the bottom plate of the steel buckle.

Double-coupling-beam structure with buckling restrained braces and construction method of double-coupling-beam structure
PendingCN112160638AReduce stressReduce section sizeGirdersProtective buildings/sheltersEarthquake resistanceBuckling-restrained brace
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.
