In recent years, several studies have investigated the sliding slab track for railway bridges.
In the design of sliding slab tracks, one of the most important considerations is to evaluate the shear capacity of the lateral supporting concrete blocks in which dowel rebars are embedded.
The predictions of the dowel behavior of rebars by existing models are considerably different.
Therefore, in this study, the actual dowel behavior of the rebars embedded in a small concrete block was extensively investigated through experiments.
Test variables were concrete compressive strength, dowel rebar diameter and yield strength, specimen thickness, and dowel rebar spacing.
Existing model predictions were considerably different from test results.
The maximum dowel force increased as concrete compressive strength and dowel rebar diameter increased, while it did not increase considerably with other test variables.
Unlike in existing models, the shear slip at the maximum dowel force decreased as the dowel rebar diameter increased.
Existing models significantly underestimated the maximum dowel force of the dowel rebars with small diameters and overestimated it for the dowel rebars with large diameters.
This work can be useful for developing a more rational model to represent the actual dowel behavior of the rebars embedded in small concrete blocks.
