A5.2- A simply supported beam with the given cross-section, as shown in Figure 2, is subjected to
factored uniform load of 50 kN/m. The designer would like to cut-off 2-30M bars where they are no
longer required by the design.
Determine the cut-off point for 2-30M bars according to CSA 23.3 requirements.
Given: Concrete: Normal density with f'c = 30 MPa
Reinforcement: Uncoated rebars with fy = 400 MPa
Shear reinforcement is in excess of CSA 23.3 minimum requirement: 10M

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). Please compare
your answers from these two analyses, examine some of your intermediate-stage calculation
results such as the total overburden stress at the pile tip relative to the weight of the pile, and
discuss whether or not the commonly used assumption about the total vertical stress at the
pile tip is a…
