A prefabricated frame structure self-resetting energy consumption system and its construction method

Abstract

The invention discloses a prefabricated frame structure self-resetting energy consumption system and its construction method. A self-resetting energy consumer between frames; the dry connection includes a frictional high-strength bolt connection between columns and columns and a pin-shaft connection between beams and beams artificial plastic hinge joints; the invention also discloses an assembled frame structure self-resetting Construction methods for resetting energy-consuming systems. The invention overcomes the shortcomings of the current prefabricated structural system, realizes the anti-seismic goal of "strong columns and weak beams, strong joints and weak members", and through reasonable setting of self-resetting energy consumers, the energy consumption capacity of the structural system is enhanced and the energy consumption is effectively reduced or avoided. The residual deformation of the structure has very important social value and economic significance for effectively mitigating earthquake disasters in high-intensity areas. At the same time, it simplifies the construction process and ensures the construction quality. It has strong practicability and is easy to promote and use.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to an assembled frame structure self-resetting energy consumption system and a construction method thereof. Background technique [0002] The prefabricated structure has the advantages of high production efficiency, short construction period, small environmental impact, sustainable development and less labor consumption, and it is widely used in the field of building structures. The development of prefabricated structural systems is the only way for building industrialization, but the existing prefabricated structures used in high-intensity areas have disadvantages such as poor node reliability, poor structural integrity, large residual deformation of the structure, and insufficient energy dissipation capacity and ductility of the structure. It is often difficult to meet the stress requirements under repeated loads, and its use in high-intensity areas is limi...

Problems solved by technology

The development of prefabricated structural systems is the only way for building industrialization, but the existing prefabricated structures used in high-intensity areas have disadvantages such as poor node reliability, poor structural integrity, large residual deformation of the structure, and insufficient energy dissipation capacity and ductility of the structure. It is often difficult to meet the stress requirements under repeated loads, and the use in high-intensity areas is limited

At present, although a large number of scholars have proposed beam-column joints, the joints are close to the core area of ​​beam-column joints, and the reinforced steel bars are densely reinforced in the joint area, which makes the joint force very complicated and the construction is difficult and uneconomical, especially under the action of earthquakes. It is difficult to achieve "strong columns and weak beams" and "strong joints and weak members". It is difficult to repair after the earthquake, causing a lot of economic losses to people
