Concrete removal works from top surfaces of girder flanges delay the construction periods of RC deck replacements and are sources of the environmental problems such as vibrations and noises. To make the construction speedy and clean, authors have proposed the method to replace RC decks with steel decks with leaving original deck concretes on the girder flanges. This paper conducted static loading test. By comparing the test results and the finite element analysis used in previous paper, validity of the analysis was confirmed.
