Abstract

The invention relates to the technical field of reinforced concrete frames, and provides a reinforced concrete frame structure which comprises a plurality of frame columns and a plurality of frame beams, wherein the frame columns and the frame beams are perpendicularly arranged and connected; a frame unit is formed between every two adjacent frame columns and between every two adjacent frame beams; the frame columns are formed by pouring first concrete; the frame beams are formed by pouring second concrete; the grade of the first concrete is C50 to C70; the grade of the second concrete is C40 to C60; the yield strength of first steel bars of the frame columns is larger than or equal to 1280 MPa; the yield strength of second steel bars of the frame beams is larger than or equal to 500 MPa; and the surface of the first steel bars is provided with an anti-rust corrosion-resistant coating. The reinforced concrete frame structure has good recoverability, and reasonable weakening control on the bonding strength of the first steel bars and the first concrete is achieved, so that the performance goals that the reinforced concrete frame structure achieves small post-earthquake damage and is easy to repair rapidly are achieved.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete frames, in particular to a reinforced concrete frame structure. Background technique [0002] At present, the urbanization of our country is accompanied by the consumption of a large amount of building materials and the excessive production of low-strength steel, which has caused serious environmental problems. It is particularly important to make reasonable and efficient use of the properties of building materials and promote the development of the construction industry in the direction of energy conservation and environmental friendliness. [0003] my country is one of the most earthquake-prone countries in the world, and it is also one of the countries with the most serious earthquake disasters in the world. A large number of earthquake damage data show that the low bearing capacity and poor deformation performance of building structures are the main reasons for the serious damage ...
