Abstract

To study the seismic performance and damage evolution of recycled aggregate concrete (RAC) filled steel tube column versus RAC short beam frame, three frame specimens with different replacement rates were designed and tested under cyclic reversed loading, and the damage evolution of specimens was analyzed based on a Park-Ang double parameter damage assessment model.The results mainly show that the failure form of RAC filled steel tube column versus RAC short beam frame with different replacement rate presents brittle shear failure.The hysteretic curves of specimens present plump shuttle shape, and all the he of specimens exceed 0.3 when the experiment ends, which shows the structure having good energy dissipation ability.With the increase of replacement rate, the descending section of specimen skeleton curve presents the trend of being steeper.Compared with the specimen with 0% replacement rate, the average yield and peak load change amplitude of the specimens with 50% and 100% replacement rate are both within 5%, and the ductility coefficient decreases 9.70% and 20%, respectively.The inter-story displacement angle of specimens is within 1/107~1/95 when yielded, and it can satisfy the comfortable requirement in normal service stage of the structure.The inter-story displacement angle of specimens is within 1/39~1/36 when destroyed, which shows good collapse resistance ability.Replacement rate has little effect on the specimen stiffness degradation, and the stiffness degradation curves of the specimens with different replacement rate are almost coinciding together.At the beginning of loading, replacement rate has little effect on the damage evolution of specimens, but with the increase of loading displacement, the damage degree of specimens gradually increases with replacement rate.
