Abstract
En 中文
Experimental and numerical results are presented to investigate the compressive behavior of steel reinforced reactive powder concrete (SRRPC) columns under eccentric loads in this paper. A total of six SRRPC columns with different eccentricities and loading angles were designed and tested, and the test findings, such as failure mode, load-displacement curves, load-strain curves, and compressive capacity were discussed in detail. The results indicate that the ultimate load decreased by 68.79 % as the eccentricity increased from 0 mm to 80 mm. The ultimate load decreased by 17.71 % as the loading angle increased from 0 degrees to 90 degrees. This shows that the eccentricity has a significant effect on the ultimate load, while the loading angle has a minor effect. Based on the test result, the finite element models were established. The finite element simulations and parametric analyses were also conducted. By considering the influence of eccentricity, concrete strength, steel strength and slenderness ratio, the variation laws of ultimate load were obtained. Finally, a new calculation method is proposed for determining the compressive capacity of SRRPC columns under eccentric loads.
