Description
Technical Field
The invention relates to the technical field of steel structure nodes, in particular to a beam-column friction energy consumption node.
Background
The steel structure has the advantages of light weight, high strength, good earthquake resistance and the like, so that the steel structure is widely applied to various building structures, however, the whole structure can collapse continuously due to local damage under the action of extreme loads (such as fire, impact, explosion, earthquake and the like), and the loss of lives and properties of people is caused. For example, a collapse accident of a fujia quanzhou Xinjia wine shop is mainly caused by illegal construction, reconstruction and reinforcement, so that a certain column on one layer is deformed, a building collapses, a large number of people are trapped, and partial people lose vital signs when being rescued due to too long trapping time, so that the life safety of people is seriously harmed.
In recent years, studies of beam column joints by scholars at home and abroad mainly focus on novel joint connection modes, such as sleeve type, flange type, reinforced type, weakened type and the like, and mainly aim at high energy consumption and large earthquake. However, due to uncertainty and unpredictability of disasters (e.g., fires, crashes, explosions, earthquakes, etc.), collapse of building structures at the time of the disaster is inevitable. The beam-column friction energy consumption node for the laminated wood structure, as disclosed in the publication No. CN111749336A, comprises a connecting piece fixedly connected to the end part of a wood beam or the side wall of the wood column, the connecting piece is connected with the wood beam and the wood column through a force-bearing piece, the wood beam and the wood column are vertically arranged, the connecting piece is respectively connected with the wood beam and the wood column through a common bolt, and finally, the shape memory alloy is tensioned at the position of an opening reserved on the upper side and the lower side of the node to form the beam-column friction energy consumption node of the laminated wood structure; although it possesses and rotates power consumption device, its whole wooden beam structure's intensity is the same, consequently, when the beam column node met extremely strong vibration and takes place to destroy, the direction that the stand collapsed was unpredictable, and people can't hide according to the structure direction that collapses, causes the threat to people's life safety and property safety. Also, for example, in the rotatable self-resetting node connection structure of the fabricated concrete beam column with publication number CN111335465a and the assembly method, the strength of each part of the concrete beam is consistent, and the column can not collapse in the same direction, so people can not avoid the column according to the structure collapse direction.
