Abstract

The invention discloses a reinforced concrete frame beam structure. The reinforced concrete frame beam structure comprises stand columns, reinforcing steel bar assemblies and enhancing structures, wherein the reinforcing steel bar assemblies are arranged between two adjacent stand columns, deformation structures are configured on the reinforcing steel bar assemblies, the deformation structures are located at or near to the minimum bending moment of the reinforced concrete frame beam structure under the vertical load; the enhancing structures are at least arranged at the deformation structures. According to the reinforced concrete frame beam structure, the plastic hinge can be effectively formed while having natural hazard as earthquake due to the fact that the deformation structures and the enhancing structures are adopted, and the energy-consuming mechanism of strong column and weak beam is achieved.

Description

technical field [0001] The invention relates to the field of civil construction, in particular to a reinforced concrete frame beam structure. Background technique [0002] my country is an earthquake-prone country, and earthquakes pose a huge threat to people's lives and property safety. Through post-earthquake investigation and analysis, it was found that most of the damage caused by the earthquake was caused by the collapse of houses. Therefore, preventing or limiting the collapse of houses under the action of earthquakes is the key to earthquake resistance. [0003] After a long period of development in structural engineering, many anti-seismic, vibration isolation and energy dissipation technologies have been developed in the field of seismic resistance. A plastic hinge is formed, and the seismic energy is dissipated through the rotation of the plastic hinge. [0004] For reinforced concrete structures, the formation of plastic hinges at the beam ends is the most reas...
