Problems solved by technology

[0004] Reinforced concrete frame structure is one of the most used structural forms in building structure engineering. Although a lot of research has been done on the seismic design of reinforced concrete frame structure at home and abroad, almost none of the existing reinforced concrete frame structure systems have self-resetting functions. Damaged in earthquakes and difficult to repair

Abstract

The invention discloses a reinforced concrete frame column with a resetting function. The reinforced concrete frame column comprises a concrete column and a base. The concrete column and the base areindependently poured. The base is the base of a cup rabbet. The lower end of the concrete column is arranged in the cup rabbet of the base. Prestressed steel bars penetrate through the column top of the concrete column to the column feet and are connected with the base through anchorage devices in an anchoring mode. The concrete column and the base are connected into one part. Elastic pads are arranged between the contact faces between the column feet in the cup rabbet of the base and the base in a filling mode. The arranged three sets of defense lines can act jointly under action of an earthquake, the structure consumes seismic action in a swinging mode, excessive deformation is not generated, concrete of column feet is not severely damaged, important components of the structure are not damaged or only slightly damaged, and therefore the building structure does not collapse and is not damaged, and can be in use continuously after simple repairing.

Description

technical field [0001] The invention belongs to the technical field of seismic design of reinforced concrete frame structures in civil engineering, and in particular relates to a reinforced concrete frame column with self-resetting function. Background technique [0002] Earthquake is a sudden, unpredictable and devastating natural disaster, which poses a serious threat to human life and property safety. From the serious consequences of the earthquakes we have concluded, the earthquake itself cannot harm people, and most of the casualties or property losses are caused by the collapsed buildings in the earthquake. Therefore, the anti-seismic design of buildings to achieve the goal of "not collapsing in large earthquakes", so that the buildings have certain anti-seismic performance and anti-collapse ability is an important means to ensure the safety of people's lives and properties. [0003] Traditional buildings mainly rely on the material deformation of the structure itself...
