Web friction energy consumption type round steel pipe concrete column-steel beam connecting node with self-resetting function

Abstract

The invention discloses a web friction energy consumption type round steel pipe concrete column-steel beam connecting node with a self-resetting function. The steel beam connecting node comprises a round steel pipe concrete column, an H-shaped steel beam, a leveling member, a channel steel web friction piece, a connecting plate and a plurality of steel strands without bonding pre-stress; the leveling member is buckled on the side surface of the round steel pipe concrete column, the channel steel web friction piece is arranged on the web plate of the H-shaped steel beam, the connecting plate isfixed on the end part of the channel steel web friction piece, and the connecting plate, the leveling member and the round steel pipe concrete column are fixedly connected, the channel steel web friction piece is slidably connected with the web plate of the H-shaped steel beam. A transverse stiffening rib is fixed on the H-shaped steel beam, each one of the steel strands without the bonding pre-stress sequentially passes through the transverse stiffening rib, the leveling member and the round steel pipe concrete column, and the H-shaped steel beam and the round steel pipe concrete column arecompacted; the anti-seismic performance and self-resetting capability of the node are excellent.

Description

technical field [0001] The invention belongs to the technical field of building structures, and relates to a web friction energy-dissipating circular steel pipe concrete column-steel beam connection node with a self-resetting function. Background technique [0002] Due to its high strength, light weight and good ductility, steel structures have been widely used in high-rise and super high-rise structures. However, a large number of brittle failures will occur in the beam-column welded joints of steel structures during earthquakes, which seriously affects the structural safety and brings great inconvenience to the post-earthquake structural repair. This makes people re-examine and seek better structural systems. At present, for steel structures, prestressing is mainly used to achieve the goal of structural self-resetting and post-earthquake recovery of structural functions. [0003] Undoubtedly, the construction of nodes is very important to form a reliable structural syste...
