A self-resetting shear-constrained buckling type damage controllable assembled beam-column joint

Abstract

A self-resetting shear-constrained buckling damage-controllable assembled beam-column joint, including prefabricated columns (1), prefabricated beams (2), pins (8), shear-buckling plates (9) and elastic members ( 12), the prefabricated column (1) and prefabricated beam (2) are fixedly connected to the column double T-shaped connecting plate (6) and the beam T-shaped connecting plate (7), respectively, and the column double T-shaped connecting plate (6) and the beam The T-shaped connecting plate (7) is hingedly connected by a pin (8); the shear-buckling plate (9) is constrained between the first restraining plate (10) and the second restraining plate (11) by bolts; the shear-buckling The plate (9) and the elastic member (12) are respectively fixed between the column double T-shaped connecting plate (6) and the beam T-shaped connecting plate (7) by bolts and clamps (13). The invention concentrates the deformation and energy consumption of the beam at the connection position, realizes energy consumption and bending rigidity provided by multiple steps, avoids relatively large plastic damage to components, and can quickly recover structural functions.

Description

Technical field [0001] The present invention relates to a mounting structure node technology, mainly used for assembly of Joints frame structure. Background technique [0002] The construction industry as a pillar industry of the national economy, mainly resource-dependent factor inputs, massive investment-led development, industrialization, low level of information, extensive mode of production, labor efficiency is not high, a large consumption of energy resources, lack of scientific and technological innovation more prominent issues. In recent years, countries around the proposed development strategy building direction of industrialization and toughness urban and rural areas, the development of prefabricated construction methods and technology to become a necessary requirement to restore function to promote the building of industrialization and development of the structure and function recoverable. [0003] Seismic performance system comprising prefabricated reinforced concrete...

AI Technical Summary

Problems solved by technology

At present, most of the research on the connection of prefabricated concrete joints focuses on strengthening the seismic performance of the joint itself. Further research and development is needed for the connection form that takes into account the simplicity and efficiency of construction and installation, excellent seismic performance, adaptability to external loads of different strengths, and recoverable functions.
