Experimental And Theoretical Study Of Transferring Structure For Steel Reinforced Concrete Beams

For steel reinforced concrete (SRC) transferring frame as a new type of structure, some experimental and theoretical studies have been carried out by some scholars at home and abroad. Based on the research on SRC frame, through a pseudo-static test of a SRC transferring frame a shaking table test of a whole frame model with SRC transferring story and a finite element analysis, the aseismic capabilities under the action of earthquake between SRC transferring structure and the whole frame with SRC transferring story are studied deeply. At the same time, through a field measurement and theoretical computation, the static behaviors the creep and the shrinkage deformation of SRC beam transferring structure are studied during the whole construction process.The behaviors of SRC beam transferring structure, which is the major research of this dissertation, is studied from four aspects: (1)Pseudo-static test of transfer structure shaking table test of a whole frame model with transferring story and a field measurement; (2)Push-over analysis; (3)the test research and theoretical analysis of joints for SRC transferring frame; (4)the research on the creep and shrinkage of SRC transfer beams.Some aseismic behaviors of transferring structure, such as the hysteresis behaviors, energy dissipation capacity and the failure patterns, are carried out by the pseudo-static test and the shaking table test. The static behaviors and deformation characteristic of SRC transfer beams, with the support column on transfer beams, are surveyed at field measurement during the whole construction process.The research results show that the SRC transfer structure , in which the hysteresis loops is plump and lateral stiffness is quite large, meets the aseismic requirements. And the connection between SRC transfer frame or reinforced concrete (RC) frame and the SRC column of transferring frame are the weak location of the whole frame under the action of seism.Through push-over analysis, the produce order and the mechanism of the plastic hinges in SRC beams for transferring structure are disclosed. By capacity spectrum method, the aseismic capacity of frame-shear wall structure with SRC transfer story is evaluated.The dynamic character of the joints for SRC transferring structure is studied under...
