Theory And Method For Design Of Pre-stressing Concrete Fabricated Frames

Subassemblage and Prestressing concrete frames are assembled by precast prestressing beams and columns with tendons in the joints of the frames.These beams and columns are hoisted in site and the tendons are passed through the moire pipes.So prestressing force are brought to the joints of the frame.These tendons also can assume the moments at the end of the beams in ordinary condition. By way of these tendons,precest beams and columns can be assembled conveniently,and the joints and frame are monolithic and continuous.Consequently,compared with common reinforced concrete frams,this kind of frame systems possess higher reliability and solved the problems in the process of assembling Prestressing Concrete frames.Also it forms the framework of Subassemblage and Prestressing Concrete Frames,and explores a new way for industrial production of prestressing structures, based on analysis about the experiments of the reversed cyclic loading on the beam-column, the seismic design method of the prestressed subassemblage frames, the principle of the analysis about the internal forces and the seismic method of the structure are established, and then the global forces analysis method under the redistributed in...
