Experiment Study on Reinforced Concrete Spatial Joints Subjected to Cyclic Loading

Abstract:

Experiments on reinforced concrete frame spatial joints are conducted under low level cyclic loadings.The seismic performance of the spatial joints is investigated,including failure mode,hysterisis curve, stiffness degradation,energy dissipation and displacement ductility.The experiment result shows that the column-hinge damage mechanism had happened and the bearing capactity ,energy dissipation character and displacement ductility had decreased under the oblique direction earthquake effect.The aseismic designing method should consider the oblique direction earthquake effect.
