Abstract: The goal of this study is to obtain the withdrawal capacities or Chengal Dowelled connection with the effect of various dowel embedment depths. The embedment depth tested for this study are 30, 60, 90 and 120 mm. Withdrawal test was used in order to obtain the withdrawal capacity using Shimadzu Testing Machine with 50 kN capacity and referring to ASTM D-1037. The samples were prepared referring to National Design Standard (NDS). The average withdrawal capacity of Chengal dowelled connection with 30, 60 90 and 120 mm embedment tested was 1.27 kN (coefficient of variation [COV] 50.5%), 1.79 kN (COV 50.2%), 1.71 kN (COV 53.8%) and 1.90 kN (COV 74.55%) respectively. This study generates data that prove the highest embedment depth has the higher withdrawal capacity. Nevertheless, the percentage different of withdrawal capacity between 120 mm and 60 mm embedment depth is only 6.3% which shows that double the embedment does not contributes to double its strength.
