Bond-slip behavior between concrete and deformed rebar at ...

The mesh size of the deformed rebar is set to 4 mm. In order to truly reflect the local bond behavior of the interface between the deformed rebar and the concrete, the concrete was established with a mesoscale model. The propagation process of cracks in concrete can be better described by the mesoscale model.

Bond-slip behavior between concrete and deformed rebar at ...

Moreover, the bond failure mechanism between deformed rebar and concrete was discussed. Subsequently, the influence of thickness to diameter ratio, elevated temperature and cooling down on the bonding behavior was discussed using the mesoscale numerical model. The results show that the failure mode and the bond stress-slip curve of the specimen are obviously related to the ratio of

15/04/2016  Precast concrete beam–column sub-assemblages may exhibit pull-out failure of reinforcing bars embedded in the middle joint when subjected to column removal scenarios. This failure mode has to be considered in analytical study through a component-based joint model.
