Transcribed Image Text:The cross section of a beam is shown in the figure is
reinforced with 5-28 mm diameter bars placed at
100 mm from the bottom fiber. The beam is
expected to carry a service moment of 280 kN-m.
Use f'c=28 MPA and fy=280 MPa. All dimensions are
in millimeters. Using WSD method, calculate the
following:
1. Cracking moment of the section.
2 Compressive stress on the concrete.,
3. Tensile stress on the steel.
4. Compressive force on the concrete.
