Self-resetting buckling-constrained central bracing system with tubular crossed plates for industrial fabricated multi-storey and high-rise steel structures

Abstract

The invention relates to a self-resetting buckling-constrained bracing central system with tubular crossed plates for industrial fabricated multi-storey and high-rise steel structures. The self-resetting buckling-constrained bracing central system can be quickly mounted and comprises a steel structure body plate rack, self-resetting bracing members and a column system. The steel structure body plate rack comprises foundation plate racks and floors. Wide beams (3), narrow beams (4) and column bases (7) are assembled to form the foundation plate racks in a factory, the foundation plate racks are integrated with the floors, steel channels are welded to one another to form the wide beams and the narrow beams in the factory, and pipelines penetrate the steel channels of webs of the wide beams and the narrow beams, so that the foundation plate racks A, B and C can be formed; joints of the foundation plate racks and the column bases and joints of the wide beams and the narrow beams are correspondingly respectively connected with one another through high-strength bolts and are partially welded, and the column bases are connected with columns through high-strength bolted flanges. The self-resetting buckling-constrained central bracing system with the structure has the advantages of high construction speed, high structural bearing capacity, good lateral displacement resistance, zero pollution and the like.

Description

technical field [0001] The invention relates to a novel structural system, in particular to an industrialized assembled steel structure central support system applied in the construction field. Background technique [0002] The construction of ordinary steel structures uses a lot of welding on site, which not only affects the construction speed but also makes it difficult to control the construction quality. In recent years, there have been numerous engineering quality problems caused by the construction quality of steel structures, and on-site welding is one of the most important Factors, on-site welding quality is not easy to control, and it causes great pollution to the environment. [0003] The traditional reinforced concrete structure requires on-site binding of steel bars and pouring of concrete, which requires a lot of labor and maintenance time, and the project cost is greatly increased. And a large amount of construction waste is generated when the building is demo...

Problems solved by technology

However, the residual deformation produced by traditional buckling-resistant braces under strong earthquakes is still unrecoverable, and traditional buckling-resistant braces also have many problems such as difficult control of machining accuracy caused by concrete peripheral restraint members, and heavy wet work workload.
