Reinforced concrete frame structure
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.
本发明涉及钢筋混凝土框架技术领域，提供一种钢筋混凝土框架结构，包括：多个框架柱和多个框架梁，框架柱与框架梁垂直设置，并连接，相邻两个框架柱以及框架梁之间形成一个框架单元；框架柱由第一混凝土浇筑而成，框架梁由第二混凝土浇筑而成，第一混凝土的等级为C50‑C70，第二混凝土的等级为C40‑C60，框架柱的第一钢筋的屈服强度大于或等于1280MPa，框架梁的第二钢筋的屈服强度大于或等于500MPa；第一钢筋的表面设有防锈耐腐蚀涂层。本发明提供的钢筋混凝土框架结构，具有良好的可恢复性能，实现了第一钢筋与第一混凝土黏结强度的合理弱化控制，从而实现了钢筋混凝土框架结构震后损伤较轻，易于快速修复的性能目标。
