| Abstract: |
To shorten the construction period, a novel deck replacement method, which does not need the removal of the entire existing reinforced concrete deck above the girder flanges, has been developed and applied to actual deck replacement work. This method is characterized by a load transfer between the girder and the deck using shear force transferring members (SFTMs). To verify this composite effect by installing SFTMs in accordance with the construction stage, field measurement and FEM analysis have been carried out. The obtained results indicate that the neutral axis in the cross section of the girder moves upward as the construction progress. If the index is defined as 100% for the fully composite state and 0% for a non- composite state, its value for the obtained state is approximately 70%, which indicates that SFTMs have sufficient functionality to enable the interaction between the girder and orthotropic steel deck effective. |
