Abstract
The invention discloses a steel pipe-reinforced concrete laminated framework structural system, which belongs to the field of structural engineering in civil engineering. The steel pipe-reinforced concrete laminated framework structural system is characterized in that laminated sections formed by wrapping reinforced concrete outside hollow steep pipes are adopted for beams and columns of the system. The hollow steel pipes are adopted inside, and the sections are unfolded, so that high rigidity is realized, the dead weight of the structure is reduced effectively while the using amount of concrete is reduced, and the acting force in earthquakes is reduced; and meanwhile, good fire-proof and corrosion-resistant protection is provided for the steel pipes by using the wrapped reinforced concrete. In node regions of the system, steel pipes in columns are connected with each other, and steel pipes in beams are welded on the steel pipes in columns through reinforced ring plates. Column longitudinal bars are arranged in a through way; a part of beam longitudinal bars go deep into nodes after bypassing the steel pipes in columns, and a part of beam longitudinal bars are welded on the steel pipes in columns; and beam and column stirrups are thickened appropriately in the node regions. The steel pipe-reinforced concrete laminated framework structural system is applied to the structural forms of frameworks, framework-shear force walls and the like, and is suitable to be taken as a main body structural system of large-sized high-rise, super-high-rise or huge structures.
Description
Technical field
The invention belongs to the Structural Engineering field in the civil engineering, particularly a kind of steel pipe-reinforced concrete sandwich frame structure system.
Background technology
In recent years, along with the fast development of China's economy and improving constantly of building structure technology, various places constantly increase the demand of high level, super highrise building and landmark building, so that the construction of mammoth structure has had unprecedented development.At present, the main Types of mammoth structure employing comprises reinforced concrete structure, pure steel structure and steel-concrete combined structure.Wherein, the combining structure such as concrete filled steel tube, steel reinforced concrete, owing to can give full play to steel, concrete bi-material advantage separately, have that intensity height, rigidity are large, a superior performance, the advantage such as good in economic efficiency, in mammoth structure, obtain using more and more widely.Mammoth structure is as important heavy construction, and its safety in all kinds of disasters is the guarantee of people's lives and properties.Because the mammoth structure quality is large, the active force that bears in earthquake is also relatively large; Simultaneously, mammoth structure mostly is high-rise, Super High, and the fire-fighting difficulty is large, and fire resistance is had higher requirement.Adopt more rational structural system, improve the performance of combating a natural disaster of mammoth structure, become the new demand of modern architecture development.Therefore, clear and definite in the urgent need to a kind of power transmission, overall performance good, can satisfy every building function, has simultaneously the structural system of good antidetonation and fire resistance, adapt to the requirement of mammoth structure development.
