Abstract:
Bridges in Texas often incorporate long steel girder spans immediately adjacent to shorter prestressed concrete girder spans. In such cases, when the steel and concrete girders meet end to end over a common support (a bent), the two members are usually different depths.
This geometric problem is commonly resolved in one of two ways:
*A step is sometimes placed in the bent cap to accept the shallow concrete girder on one side and the deep steel girder on the other.
* The deep steel girder can be made shallower at its terminal end, or dapped, to rest at the proper elevation on a flat bent cap end to end with the concrete girder.
