Abstract

Abstract

In this paper，it was carried out nonlinear numerical simulation of six axial specimens and nine eccentriccompression specimens of steel reinforced recycled aggregate concrete columns using open-source earthquakeengineering simulation system OpenSees． It was also analysed the effects of the recycled aggregate replacement rate，slenderness ratio and concrete strength on the bearing capacity of the exially loaded specimens，and also analyzed theeffects of the recycled aggregate replacing rate，relative eccentricity and concrete strength on the bearing capacity ofthe eccentrically loaded specimens． In the analyzing process，the column section was fine-divided and different fiberswere defined to simulate the appropriate material properties． And then，a model of SＲＲAC column was establishedbased on the nonlinear beam-column element． The comparative analysis of the simulation results and the experimentalresults indicates that OpenSees Program can be used in simulating the loading process of steel reinforced recycledaggregate concrete columns effectively．
