WebThe continuity leads to continuity moments, and reinforcements in the diaphragm and the connecting ends of the girders are required to resist these moments and prevent cracks. WebThe bridge was con- structed using AASHTO Type II girders with mild reinforce- ment extending into the continuity diaphragms to make a pos- itive moment connection. The girders were also embedded several inches into the continuity diaphragm. The behavior of this bridge was investigated by monitoring crack widths and performing a load test.
