Abstract
A method for connecting precast concrete girders by tensioning temporary tendons lower than the neutral axes of girders, supporting the girders at the both ends, placing concrete into the gap, tensioning the tendons which connect adjacent girders while releasing the temporary tendons in order to reduce the bending moment at the midspan of girders.
