摘要：
Seismic performance of a hybrid structure with SRC frame and steel frame strengthened concrete core tube was carried out with shaking table test. A 1∶10 scaled model with 17 floors for this structural system was designed and tested to obtain comprehensive anti-seismic performance corresponding to several seismic waves. Both dynamic characteristics and responses of acceleration, velocity, deformation and failure mechanism, cracking pattern for model structure were discussed. Effect of steel frame in core tube on the whole lateral capacity and deformation performance was analyzed. The results show that main cracks of this structural system originate at the joint connections between outer steel strengthened frame and core tube for different types and intensity of ground motion, and then develop to the coupling beams at the core tube. Steel frame in core tube and SRC frame part are both kept in elastic condition after serious damages occurred in shear walls. The whole structure system could form a second seismic fortification easily with definite force transmission mechanism and has a good seismic performance. © 2016, Editorial Office of Journal of Building Structures.
