The building block is simple to manufacture and process, short in construction period, light in weight and the like, and is widely applied to high-rise buildings and large-span buildings. And because steel can be recycled, the steel structure is a reusable, environment-friendly and energy-saving structure, and meets the current requirements of social sustainable development, so that the steel structure is more and more applied to the field of buildings. Therefore, the steel structure is known as one of "green structures" of the 21 st century.
In the steel structure, the steel frame is widely applied due to the advantages of simple structure, easy construction, good earthquake resistance and the like. The static load is transferred by the beam-column joint in the steel frame, so the structure is complex; the anti-seismic properties such as the plastic deformation capacity and the energy consumption capacity of the structure are closely related to the beam-column nodes; the failure of the beam-column joint is difficult to repair and can result in the collapse of a local floor or even the collapse of the entire structure. Therefore, the beam-column joint is related to the safety and stability of the steel frame, and the research on the performance of the beam-column joint is the core of the research on the steel structure.
The circular steel tube is simple to manufacture, attractive in shape, simple and convenient to design, strong in stability and good in pressure-bearing performance, and therefore, the circular steel tube is widely applied to building structures. However, because the axial bearing capacity of the reinforced concrete frame is relatively insufficient, the frame node part is the part which is most prone to deformation or damage in engineering practice, and the reinforced concrete frame has practical significance for the research on a node reinforcing method.
