Shear Capacity Of Subassemblage And Prestressed Concrete Frame Joints

Prestressed Subassemblage concrete frame is assembled by precast prestressed 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 is 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, precast beams and columns can be assembled conveniently, and the joints and frame are monolithic and continuous. Consequently, compared with common reinforced concrete frames, this kind of frame systems possess higher reliability and solved the problems in the process of assembling Prestressed Concrete frames. Also it forms the framework of Prestressed Subassemblage concrete frame, and explores a new way for industrial production of prestressed structures.The paper based on experiment of two subassemblage and prestressed concrete frames under low reversed cyclic loading. Pressure on pre-fabricated prestressed concrete frame joints cracking the core and shear performance, given the shear cracking and checking formula and analysis of the sub-node shear bending moment on the properties of paper used ANSYS KJ-2 reverse reaction force loading a simulation of surcharging hope assembly of prestressed concrete framework of research and applications proposal guide.
