Abstract

The controllable rocking reinforced concrete frame (CR-RCF) with column-end-hinge Joints is a new type seismic-reducing structural system with special design for the column-beam joints and the application of structural control theory and technology. Based on the comparative shaking table tests of a 1/3 scale 3-story-3-span CR-RCF with column-end-hinge Joints and a same size conventional reinforced concrete frame, the dynamic characteristics, acceleration reponse and displacement response of the model structures under different earthquake levels are discussed to validate the seismic performance of CR-RCF with column-end-hinge Joints. Test results indicate that the CR-RCF with column-end-hinge Joints has a definite centralized energy dissipation mechanism, excellent self-centering capability during earthquake and it is a damage-free structural system with the main bearing component remaining intact under major earthquake.
