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, China's output of steel was broken through 700,000,000 tons of high pointes in 2011, was sure to occupy output of steel first place, countries in the world in continuous 16 years, and 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's conduct is the country of construction scope, steel output maximum in the world, and the development of house (comprising dwelling house) steel work seriously lags behind.2,000,000,000 square metres of China's annual town and country newly constructed house areas wherein are the high energy consumption building more than 80%, China unit's building area energy consumption is more than 2 times of developed country.
At present, the system research to the high-rise steel structure dwelling house both at home and abroad is in the starting stage, and the system innovation of industrialization assembling high-rise steel structure is imperative.Adopted a large amount of welding during the construction of traditional housing building of steel-structure, speed of application is slow, and seriously polluted to environment the most important thing is that the quality of weld seam should not be controlled, and 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 is out of shape greatlyyer, and the destruction that causes non-structural element is not easily brought into play the superiority of steel house fully.The how high-rise assembling type steel structure framework of industrialization-center support system is based on module design, component standardization, promote industrialization with standardization, promote the basic development principle of industrialization with industrialization, increased horizontal and vertical center support on the basis of steel frame, improve the lateral rigidity of structure, improved the deformation performance of structure.
Traditional structure design with analyze, generally beam column node processing in the frame construction is become desirable rigid joint or hinged joint.Because rigid joint bearing capacity and rigidity are all very big, thereby be considered to a kind of ideal shock-resistant node form usually and the node that is widely used in the earthquake zone frame construction connects and designs.But the earthquake experience shows: the rigidity bean column node of building connects and brittle fracture in various degree occurred.Adopt the steel framed structure of welding rigid joint because of node ductility difference brittle fracture to take place easily, and difficulty of construction is also big; Though hinged joint simple structure but rigidity and energy-dissipating property are poor is unfavorable to the antidetonation of structure; Have only the semi-rigid node of connected mode simple and fast to have the two advantage concurrently, have higher strength and stiffness and ductile performance and energy-dissipating property preferably, thereby reduced earthquake to a great extent.
Summary of the invention
The present invention proposes a kind of assembling type steel structure center support frame system that belongs to technical field of structural engineering.Its purpose is in the production of steel structure system and construction, with modularization, and batch production, standardization and assemblingization combine, realized batch production production, assemble fast at the scene, under the prerequisite that guarantees construction quality, improve speed of application, reduced the construction period, reduced construction costs.This structural system can the realization body steel structure frame and the Fast Installation of lateral resistant member, and can resist earthquake and wind load, has embodied the advantage of steel work.And bean column node connects the semi-rigid node of employing among the present invention, and the initial anti-side rigidity of Semi-rigid Connection Steel Frame is less, but ductility factor is bigger, and energy dissipation capacity is fine, can satisfy the design object of antidetonation under the rarely occurred earthquake effect well.
