Embodiment Construction

[0016] The invention is widely used in my country for concrete structures, and has a complete design method and design theory. With the development of the country and the improvement of people's living standards, people have higher and higher requirements for the use of buildings. Buildings tend to be more and more high-rise, super high-rise, and long-span structures, while concrete structures have limitations in these aspects. Experimental research has proved that after reasonable design, restrained buckling braces can significantly improve the performance of concrete structures, making concrete structures more widely used and more suitable for current design requirements. At present, there are many concrete structures in our country. After the baptism of time and the invasion of natural disasters, the seismic performance of many buildings has degraded. It is a waste of resources to demolish these buildings and rebuild them. Then it is a very effective method to strengthen c...

Abstract

The invention discloses a joint of a buckling restrained brace and a concrete beam, and a building unit. The building unit consists of the buckling restrained brace and the concrete beam; and the joint of the buckling restrained brace and the concrete beam is a cotter connection type joint of the buckling restrained brace and the concrete beam. The joint of the buckling restrained brace and the concrete beam is a section steel type joint of the buckling restrained brace and the concrete beam. The joint of the buckling restrained brace and the concrete beam is a combined type joint of the buckling restrained brace and the concrete beam. A reinforced concrete frame structure for preventing the buckling restrained brace not only can increase the overall rigidity and improve the structure ductility, but also can fully play a role in energy dissipation because the reinforced concrete frame structure cannot be buckling when pressed, so the reinforced concrete frame structure has important application value in the field of engineering seismology.

Description

technical field [0001] The invention relates to a building component, in particular to a restrained buckling brace and a concrete beam joint. Background technique [0002] Buckling Restrained Braces (BRBs) are called buckling restrained braces (Buckling Restrained Braces, referred to as BRBs) in Taiwan, my country. In the United States and Japan, it is called Unbonded Braces (UBB for short). The anti-buckling restraint brace is mainly composed of two parts: the inner core element and the outer restraint element. Between the two, fine stone concrete is filled to realize the restraint of the outer restraint sleeve on the inner core material and limit its buckling under compression. The concrete and core steel members are separated by a thin layer of material that allows the steel members to slide through the concrete. The core unit is generally made of steel with a low yield point, and consists of a core section, a transition section and a connecting section from the mi...
