Abstract:
To study the compression performance of the recycled concrete columns, a series of eccentric compression performance tests of full scale recycled concrete columns were carried out. Test specimen includes four full scale recycled concrete columns and two full scale ordinary concrete columns. Then, nonlinear finite element analysis using the software ABAQUS was carried out to study the effects of the recycled concrete strength, reinforcement ratio, stirrup ratio and eccentricity on the eccentric compression performance. Comparing with the experimental results, the applicability of the finite element model was proved. Test results showed that, with the increase of the recycled concrete strength, the load-bearing capacity and stiffness of the specimen were improved accordingly; with the increment of the reinforcement ratio, the load-bearing capacity increased significantly. With the increment of the stirrup ratio, the ductility increased, and the load-bearing capacity changed a little. Impact of eccentricity on the compression performance of the specimen is relatively large. With the increase of the eccentricity, the load-bearing de-creased and the ductility increased.
