We delve into the substructure, the crucial support system holding the bridge deck. You'll learn to design piers, the pillars taking the bridge's weight, and abutments providing support at the ends. Analyzing forces acting on these structures and designing them for strength and stability, even during earthquakes, is a key focus. Different pier designs and bearing systems that transfer the bridge's weight to the ground will be explored.
