Assembly concrete building can be divided into two major classes of full assembling and part assembling according to assembling degree height.Full assembling Building is generally limited to low layer or the relatively low tier building of requirements for fortification against earthquake；Part assembling concrete construction main member is general Connected using prefabricated components, at the scene by cast-in-place concrete, form the building of cast in place and precast construction.

North America region is mainly with America ＆ Canada as main because prefabricated/prestressed concrete association (PCI) studies for a long period of time With popularization pre-cast building, the Specification of precast concrete also improves very much so its assembly concrete Application in Building is non- It is often universal.The pre-cast building of North America mainly includes the big series of building prefabrication exterior wall and structure prefabricated components two, and prefabricated components are total to It is that maximization and prestressing force are combined and can optimize structural reinforcement and connecting structure with feature.Reduce and make and installation workload, contracting The short Yi works duration, fully demonstrate industrialization, standardization and Technical Economy feature.In 20th century, the pre-cast building of North America is main For the non-antidetonation fortified defence area of low layer.Due to the earthquake effect in California area, antidetonation and on the middle and senior level prefabricated is paid much attention in recent years The engineer applied technical research of structure.PCI is published recently《Precast concrete Aseismic Design》One book, from theory and practice Analyze the Aseismic Design problem of pre-cast building, the newest section for summarizing many precast construction Aseismic Designs is ground into angle system Really, to instructing, precast construction is designed and engineer applied is promoted and has very strong directive significance.

Europe is the cradle of pre-cast building, and the road of building industrialization has been begun to early in the 17th century.Second world is big After the war, due to human resources shortage, Europe further research and probe building industrialization pattern.Either economically developed north Europe, West Europe, or Eastern Europe underdeveloped, are all actively carrying out the design and construction side of prefabrication and assembly construction concrete construction always Formula.The design and construction experience of many pre-cast buildings is have accumulated, various special precast building systems and standardized general are formd Pre-manufactured product series, and a series of precast concrete engineering specifications and application manual have been worked out, to promoting precast concrete complete The application in the world serves very important effect.

Japan and South Korea have used for reference the successful experience of America and Europe, on the basis of the standardized designs construction for exploring pre-cast building. With reference to oneself requirement.Breakthrough is achieved in terms of precast construction system globality antidetonation and shock design.With representative Property achievement be two Tokyo Towers of 58 floor being built up using prefabrication and assembly construction frame structure for 2008 of Japan.Meanwhile, Japanese is pre- Concrete construction System Design processed, the standard criterion for making and constructing are also very perfect, and the prefabricated specification for using at present has《It is prefabricated mixed Solidifying geotechnique's journey } (JASSl0) and《Concrete curtain wall) (JASSl4).

China from the sixties in 20th century five begin one's study assembly concrete building design and construction technology, form one Serial assembly concrete building system, more typical building system has assembled single storey industry workshop building system, assembling Formula multistory frame building system, assembled large panel building system etc..To the application of the assembly concrete building eighties in 20th century The period of full bloom is reached, many places in the whole nation all form the assembly concrete industry of design, making and construction and installation integration Change architectural mode assembly concretes building and use the masonry building of prefabricated hollow floor as two kinds of topmost building bodies System, application popularization rate is up to more than 70%.Because there is many limitations and deficiency, China in the function and physical property of assembled architecture Assembly concrete architectural design and construction technology R ＆ D Level do not catch up with also social demand and Building technology development change. To the mid-90 in 20th century, assembly concrete building is gradually replaced by full cast-in-place concrete building system, at present except dress Wide outer with formula single storey industry workshop building system application, the engineer applied of other prefabrication systems is few.In advance The specialized research of the globality and management in design and operation of structural seismic processed is inadequate, and connector quantity is more, and high energy consumption etc. is caused Its Technical Economy is poor.It is the basic reason for causing precast construction to stagnate for a long time.
