Embodiment Construction

[0018] The invention is aimed at concrete structures which are widely used in my country, 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 ...

Abstract

The invention discloses a BRB (buckling-restrained brace) concrete frame beam-column joint, belonging to a building element. The joint disclosed by the invention consists of a buckling restrained brace and a concrete beam-column. The invention is characterized in that the BRB concrete beam-column joint can be a stud-connected joint which is a joint of the beam and column of a BRB concrete frame; the joint is an A-shaped steel joint which is the joint of the beam and column of the BRB concrete frame; the joint can be a combined joint which is the joint of the beam and column of the BRB concrete frame; and the joint is a connecting joint of a BRB and a foundation, and a joint of the BRB of the BRB concrete frame and the foundation. The joint is composed of the BRB and the concrete beam-column, therefore, the anti-seismic capability of the joint is good, and the joint can be applied to large-span and high-rise concrete frames.

Description

technical field [0001] The invention relates to a building component, in particular to a restrained buckling braced concrete frame beam-column node. 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...
