| Abstrait: |
In order to apply a Modified-VFT (MVFT) steel-concrete composite girder to a continuous bridge, this paper investigates the structural configuration of the negative bending moment region of MVFT girder. Clothoid shaped composite dowels are designed in the hogging moment zone. Comparison studies were made for different geometric parameters of the connection. With the aim to increase the crack resistance of the concrete deck in the hogging moment region of the composite bridges, Ultra-High-Performance-Concrete (UHPC) is adopted. Wet joints schemes of shear studs and CL composite dowels are analysed. |
