Dowel rebar is key parameter to control the lateral displacement in the sliding slab track. The lateral support block of the sliding slab track is supported by the dowel rebar. In this study, selected parameter (rebar diameter) was expected to affect the performance and behavior of the dowel rebar in the sliding slab track. Furthermore, evaluation of the shear behavior of dowel rebar compared to the results of the Soroushian et al. (1986) and CEB-FIP (2010).

This study was performed to analyze the flexural performance of large diameter PHC Pile reinforced with transveres and longitudinal rebar and in-filled concrete. From the flexural test result, it was found that the initial cracking strength and maximum flexural strength of composite PHC pile were approximately 400% and 345% higher than that of the conventional PHC pile.
