3342Governing Sections of the Stub Girder

Figure 33.5 and Figure 33.7 show certain circled numbers at various locations throughout the span of the stub girder. These reflect the sections of the girder that are the most important for one reason or another and are the ones that must be examined to determine the required member size, etc. These are the governing sections of the stub girder and are itemized as follows:

1. Points 1, 2, and 3 indicate the critical sections for the bottom chord.

2. Points 4, 5, and 6 indicate the critical sections for the concrete slab.

3. Point 7, which is a region rather than a specific point, indicates the critical shear transfer region between the slab and the exterior stub.

The design checks that must be made for each of these areas are discussed in the following.
