A6.1- A simply supported beam, as shown in Figure 3, is subjected to factored point load Pr=
1250 kN. The beam is designed to have 6-30M bars to resist the maximum bending moment, Mat
the section 900 mm away from the centerline of the support.
Determine the required development length for the reinforcement at the section with the maximum
bending moment. If it is not possible to provide straight bar anchorage into the left support, design
the hooked anchorage.

Please perform the tip capacity calculation two ways: For the first approach, assume that the total vertical stress at the pile tip is balanced by the weight of the pile. For the second approach, assume that the total vertical stress at the pile tip is not balanced by the weight of the pile (which means you need to include the vertical total stress term).
