A kind of assembling type steel structure center support frame system
Technical field
The present invention relates to a kind of assembling type steel structure center support frame system, belong to technical field of structural engineering.
Background technology
Join in a common effort meter according to Chinese steel, within 2011, China's output of steel breaks through 700,000,000 tons of high pointes, and within continuous 16 years, be sure to occupy countries in the world output of steel the first, developed country's steel building area accounts for overall floorage more than 50%, and Japan accounts for 80%, and China is less than 4%.China is as the maximum country of construction scope in the world, steel output, and the development of house (comprising house) steel work is seriously delayed.China's annual town and country newly constructed house area 2,000,000,000 square metres, wherein more than 80% is high energy consumption building, and unit of China building area energy consumption is more than 2 times of developed country.
At present, be in the starting stage both at home and abroad to the system research of high-rise steel structure house, the system innovation of industrialization assembling high-rise steel structure is imperative.Have employed a large amount of welding during traditional housing building of steel-structure construction, speed of application is slow, seriously polluted to environment, the most important thing is that the quality of weld seam should not control, has a strong impact on the security performance of building.
Traditional steel frame structural system, the lateral rigidity of structure is difficult to meet the demands, and distortion is comparatively large, easily causes the destruction of non-structural element, does not play the superiority of steel house completely.The how high-rise assembling type steel structure framework-center support system of industrialization is based on module design, component standardization, industrialization is promoted with standardization, the basic development principle of industrialization is promoted with industrialization, the basis of steel frame adds horizontal and vertical center support, improve the lateral rigidity of structure, improve the deformation performance of structure.
Traditional structure design with analyze, generally frame construction beam-column node processing is become desirable rigid joint or hinged joint.Because rigid joint bearing capacity and rigidity are all very large, are thus usually considered to a kind of ideal shock-resistant node form and are widely used in the node connection design of earthquake zone frame construction.But earthquake experience shows: the reinforcing beam Column border node of building connects and occurred brittle fracture in various degree.Adopt the steel framed structure of welding rigid joint, because of ductility of joint difference, brittle fracture easily occurs, and difficulty of construction is also large; Though hinged joint simple structure but rigidity and energy-dissipating property poor, unfavorable to the antidetonation of structure; Only have the structures with semi-rigid joints of connected mode simple and fast to have the two advantage concurrently, there is higher strength and stiffness and ductile performance and energy-dissipating property preferably, thus reduce earthquake to a great extent.
Summary of the invention
The present invention proposes a kind of assembling type steel structure center support frame system belonging to technical field of structural engineering.Its object is in the production and construction of steel structure system, by modularization, batch production, standardization and assemblingization combine, achieve factorial praluction, on-the-spot quick assembling, under the prerequisite ensureing construction quality, improve speed of application, decrease the construction period, reduce construction costs.This structural system can the Fast Installation of realization body steel structure frame and lateral resistant member, and can resist earthquake and wind load, embodies the advantage of steel work.And beam-column node of the present invention connects employing structures with semi-rigid joints, and the initial anti-side rigidity of Semi-rigid Connection Steel Frame is less, but ductility factor is comparatively large, and energy dissipation capacity is fine, can meet the design object of antidetonation under rarely occurred earthquake effect well.
