16.10 Determine the maximum and minimum elastic moments at the supports and midspans of the three-span<br />

continuous beam shown in Fig. 16.37. The beam has a uniform rectangular section and carries a uniform<br />

dead load of 6 K/ft and a live load of 5 K/ft. Assuming 10% maximum redistribution of moments;<br />

recalculate the maximum and minimum moments at the supports and midspans of the beam ABC. Note:<br />

Place the live load on alternate spans to calculate maximum positive moments and on adjacent spans to<br />

calculate the maximum negative (minimum) moments (Example 16.8).<br />

16.11 Repeat Problem 16.10 if the beam consists of four equal spans, each 24 ft in length (Fig. 16.39).
