Problems solved by technology

However, the current research focuses on enhancing the seismic performance of the joint itself, while the research on the adaptive control technology of the whole structure under the action of external loads of different strengths is relatively insufficient. The difficulty is relatively large, and it is difficult to achieve rapid recovery of building functions

Abstract

A self-resetting stiffness self-adaptive control assembled beam-column joint, the prefabricated column (1) and the prefabricated beam (2) pass through the column T-shaped connecting plate (6), the beam T-shaped connecting plate (7) and the pin shaft (11) Hinged connection, the saddle-shaped circular plate (8 ) and a rubber disc (9), the high elastic part (13) is tensioned and fixed by a clamp (14) and bolted to the first vertical plate (6‑1) of the column T-shaped connecting plate and the beam T-shaped connecting plate between the U-shaped slots (12) on the second vertical plate (7‑1). The invention realizes the self-adaptive control of the structure under the action of external loads of different strengths, avoids large plastic damage to the components, and can basically realize complete reset after the earthquake. replace.

Description

technical field [0001] The invention relates to an assembled structure node technology, which is mainly used for an assembled frame structure beam-column node. Background technique [0002] The traditional cast-in-place reinforced concrete structure requires a lot of labor force, high resource consumption, and great environmental impact. Its development model does not meet the current social needs of sustainable development. With the transformation of the national development strategy, the prefabricated concrete structure, as an industrialized building production mode, has attracted widespread attention due to its advantages of less labor demand, low resource consumption, low environmental pollution, high component quality, and short construction period. Relevant government departments Policy documents to promote the industrialization of construction have been issued many times, clearly requiring the vigorous development of prefabricated buildings. [0003] The node connect...
