Predicting the bond-slip relationship between concrete

2020-12-1  Several models have been proposed to predict the concrete to CFRP sheets bond behavior [ 30, 40,,,, ]. Some were proposed by adopting some assumptions then verified by test data, others were based on empirical relations calibrated with experimental results, and others were based on fracture mechanic theories.

Analysis of bond-slip between concrete and steel bar in fire

2016-1-19  This paper presents a robust model for predicting the bond-slip between the concrete and steel reinforced bar at elevated temperatures. The model is established based on a partly cracked thick-wall cylinder theory and the smeared cracking approach is adopted to consider the softening behaviour of concrete in tension. The model is able to consider a number of parameters: such as different concrete properties and covers; different steel bar diameters and geometries. The proposed model has been incorporated into the Vulcan program for 3D analysis of reinforced concrete
