Problems solved by technology
Although this joint is widely used, it has the following disadvantages: there are on-site construction welds, many construction procedures, and the quality of welding is difficult to control; there is serious stress concentration at the weld, and the weld is easy to crack under earthquake load
[0004] The post-earthquake repair of the above-mentioned bolted and welded joints and full bolted joints is extremely cumbersome, and it will cause secondary damage to the originally fragile structure after the earthquake

Abstract
The invention belongs to the field of building steel structures and discloses a single-side buckling-restrained steel beam column connection node and a steel-structure building. The single-side buckling-restrained steel beam column connection node comprises a steel beam and a steel column, and a hinge connector and an energy consumption element are arranged at the joint of the steel beam and the steel column. The hinge connector comprises a first connection plate and a second connection plate, the second connection plate is hinged to the end of the first connection plate, the first connection plate is connected to a top flange of the steel beam, and the second connection plate is connected to a flange of the steel column. The energy consumption element is connected with both a bottom flange of the steel beam and the flange of the steel column, and the middle of the energy consumption element is a weakened area. The single-side buckling-restrained steel beam column connection node and the steel-structure building have advantages that an excellent anti-seismic performance is realized, damages of the connection node can be controlled, the steel beam and the steel column are not damaged after an earthquake, and the energy consumption element can be quickly replaced and repaired on the premise that an original structure (such as a floor) is not damaged.
Description
technical field [0001] The invention relates to the field of building steel structures, in particular to a unilateral buckling-constrained steel beam-column connection node and a steel structure building. Background technique [0002] The most commonly used beam-to-column joints in steel structure houses are bolted and welded hybrid joints. It connects the steel beam flange and the steel column flange with full penetration welds, and the steel beam web and the shear plate welded on the steel column flange are connected with friction type high-strength bolts. Although this joint is widely used, it has the following disadvantages: there are on-site construction welds, there are many construction procedures, and the quality of welding is difficult to control; there is serious stress concentration at the weld, and the weld is easy to crack under earthquake load. These deficiencies greatly reduce the ductility and energy dissipation capacity of the node, and the earthquake resis...
