Load Combinations
Consider the cantilever beam shown in Figure 1, which is loaded at its tip with a concentrated
dead load Pp
5 ft long and is anchored to a stiff column, as shown.
10 kips (ignore the self-weight). The beam is
20 kips and a live load PL
1. Explain which of the load combinations discussed in class governs the design. For this
governing load combination, calculate the factored load Pu and draw the corresponding
shear force and bending moment diagrams of the beam. Why is it unnecessary to draw
design envelopes?
