Abstract
Recently, many bridges become not only functionally obsolete of bridge dick due to inadequate width but also structurally deficient of substructure due to erosion. In these case widening is almost always more economical than complete replacement, and therefore there is a need to make available the results of research and field experience pertaining to the widening of bridge substructure. But, an experimental study for the guarantee of unification between existing and new substructure with post-installed concrete set anchor is so insufficient that the development of post-installed concrete set anchor system for the unification should be settled promptly. The objective is to investigate the effects of anchor embedment depth and concrete strength on pullout characteristics of post-installed concrete set anchor embedded in plain concrete. The effects of embedment depth variable is depending on concrete strength as strong as concrete strength is pullout load is high. Regardless of concrete strength, embedment depth that less than 6 times appeared concrete failure mode but for embedment depth that over 8 times concrete strength has no affection on failure mode.
