Abstract:
Taking an eighteen-story precast monolithic concrete frame engineering as background, designing the specimens in terms of the objective of strong column-weak beam and strong joint-weak element, the full-scale model tests of two different typical shear-span ratio connections with composite beams and cast-in-place columns were carried out under low cyclic loading. Failure mode, hysteresis curve, displacement and ductility, energy dissipation capacity, shear deformation of precast monolithic concrete frame exterior connections were systematically studied. The results show that the two precast monolithic concrete frame exterior connections have large safety margins under low cyclic loading. The connections with normal shear-span ratio fail in bending and short shear-span ratio fail in shearing at the fixed beam ends. The longitudinal steel bars at the fixed beam end yield while the longitudinal steel bars in the column and the joint hoops keep in elastic state. The connections with normal shear-span ratio have better energy dissipation than connections with short shear-span ratio.
