The following shows the cross section and bending moment diagram of a two-bay continuous beam. The beam dimensions are 24" wide by 28" deep. Stirrups are #4. The maximum bending moments for the continuous beam are shown on the diagram. (Negative indicates tension at top and positive indicates tension at bottom). Determine the required effective depth, area of steel and number of top and bottom reinforcing bars using the sizes indicated.

Question

The following shows the cross section and bending moment diagram of a two-bay continuous beam. The beam dimensions are 24" wide by 28" deep. Stirrups are #4.

The maximum bending moments for the continuous beam are shown on the diagram. (Negative indicates tension at top and positive indicates tension at bottom). Determine the required effective depth, area of steel and number of top and bottom reinforcing bars using the sizes indicated.

What would be the minimum width of the beam if the longitudinal steel is 7 - #8 bars
and the center-to-center distance between bars is 3 times bar diameter?
