Abstract:
The push-out tests on 16 limestone manufactured sand recycled coarse aggregate concrete(MSRAC)-filled square steel tube specimens were conducted, and the influences of strength grade of MSRAC, stone powder content, and width-to-thickness ratio of steel tube on the bond-slip behavior between limestone MSRAC and square steel tube were investigated. Based on the free end slip curve of the specimen, the development process and internal mechanism of the bond-slip behavior were analyzed. The average bond strength was compared with that of pebble MSRAC-filled square steel tube. The bond-slip constitutive model of pebble MSRAC in square steel tube was employed to simulate the bond-slip curve of the limestone MSRAC in square steel tube and verified with the test results. The bond-slip behavior of the specimen was affected by the position of the measured point. By introducing the position function, a bond-slip constitutive model which can reflect the local bond slip law was proposed. The results show that limestone MSRAC-filled square steel tube has experienced four stages during the testing, including cementation, slipping, frictional resistance, and after-slipping, respectively, and it has higher bond strength comparing with that of pebble MSRAC. Comparing the calculated values with the test values obtained from the constitutive model and analyzing its error, it is found that the relative error between the bond strength and slip value fitted by the bond-slip constitutive model of pebble MSRAC in square steel tube and the test values is less than 5%, and the standard deviation is less than 0.05, which proves that the constitutive model has good applicability.
