    Abstract: In this study, the behaviour of the column-foundation connection 
  in the precast reinforced concrete structures was observed and studied. Two 
  different type of precast columns with same socket foundation were chosen and 
  based on previous studies that were carried out by Canha in 2004 and Ebeling 
  in 2006. This observation will be based on the compression of ultimate load 
  between experimental models in term of comparison, assumptions, recommendation 
  and aspects in changing the materials and details in the column part.
