Connecting node plate with sliding end plate for buckling-restrained brace

Abstract

The invention provides a connecting node plate with a sliding end plate for a buckling-restrained brace. The connecting node plate comprises a center plate, a first rib plate, a second rib plate, a horizontal end plate, a first horizontal cushion plate, a second horizontal cushion plate, bolts and non-adhering layers, wherein the horizontal end plate is vertical to the center plate, and is fixedly arranged at the lower end surface of the center plate; the first horizontal cushion plate and the second horizontal cushion plate are respectively arranged at the upper surface of the horizontal end plate, and are respectively positioned at the two sides of the center plate; first through holes are formed in the horizontal end plate, first mounting holes are formed in the first horizontal cushion plate and the second horizontal cushion plate, and the non-adhering layers are respectively arranged at the bottom surface of the horizontal end plate, between the horizontal end plate and the first horizontal cushion plate, and between the horizontal end plate and the second horizontal cushion plate. The connecting node plate has the advantages that the adverse influence of beam column opening and closing effect to the node plate is decreased, the influence of the node plate to the beam column rigid area effect and computing length is decreased, the stress distribution of the node plate is more uniform, and the design and construction are simpler and more convenient.

Description

technical field [0001] The invention relates to the technical field of civil engineering structures, in particular to a connecting gusset plate with a sliding end plate used for anti-buckling supports. Background technique [0002] Anti-buckling bracing is currently being used as a new energy-dissipating and shock-absorbing component in civil building structures, especially in multi-story buildings. dissipate seismic energy. In practical applications, buckling-resistant braces must be connected to beams and columns through gusset plates. figure 1 It is the structural diagram of the overall connection between buckling-resistant braces and beams and columns, figure 2 A schematic diagram of the connection gusset plate structure for traditional buckling-resistant braces, such as figure 1 , 2 As shown, the traditional connection method is to connect the gusset plate with the flange of the steel column and steel beam through fillet welds, and the buckling-resistant brace conn...
