Replaceable energy-dissipating connection components for beam-to-column connections in fabricated concrete frames

Abstract

The present invention proposes a replaceable energy-dissipating connection assembly for beam-to-column connections of fabricated concrete frames. The upper side and / or the lower side of the end, including one or more energy-dissipating core steel plates (1) arranged side by side, an anchor block inside the column ( 2), the anchor block (3) in the beam located at the other end of the energy-dissipating core steel plate (1) and embedded in the corresponding position of the concrete at the beam end during the prefabrication stage, and the restraint system (4) surrounding the energy-dissipating core steel plate (1); The core steel plate (1) and the anchor block in the column (2) and the anchor block (3) in the beam are reliably connected to form a continuous force transmission component. The application of replaceable energy-consuming connection components meets the requirements of building industrialization development, has the advantages of mass production and rapid assembly construction, and at the same time greatly reduces the difficulty of post-earthquake repair of the structure.

Description

technical field [0001] The invention belongs to the field of construction engineering and relates to an assembled concrete frame structure, in particular to a replaceable energy-consuming connection assembly applied to the beam-column connection of the assembled concrete frame. Background technique [0002] In recent decades, prefabricated concrete structures have been favored by engineers more and more due to their characteristics of industrial production and prefabricated construction, and have been widely used and developed rapidly all over the world. With the in-depth study of performance-based seismic design theory, people have higher and higher requirements for the repairability of structures after earthquakes, and the research and application of high-ductility energy-dissipating components have received more and more attention. In countries and regions such as China, the practice of adding ductile energy-dissipating components to prefabricated structures has become in...

Problems solved by technology

The damaged engineering structure has weakened ability to bear loads and effects, deteriorated mechanical performance, and reduced structural safety.

Under the action of earthquakes that may occur in the future, it is more likely that the structure will lose its integrity due to the accelerated failure of the damaged parts, and in serious cases, it may collapse, causing huge losses of people's lives and property.
