Q2: For the cantilever beam Shown in Figure 2 following: The reaction at fixed end Rcy The reaction at the fixed end Mc The shear force at B The bending moment at B Draw the shear force and bending moment diagrams for the beam W=4 kN/m p=26 kN B LI=2 L2 =2 Figure 2

For the beam shown: (a) determine the distance a for which the maximum positive and negative bending moments in the beam are equal; and (b) draw the corresponding shear and bending moment diagrams for the beam.

Solve Problem 15.4 for the loading shown in Fig. P15.4 and the support settlements of 1 in. at B and 14 in. at C. FIG. P15.4, P15.7

A beam is part of the framing system for the floor of an office building. The floor is subjected to both dead loads and live loads. The maximum moment caused by the service dead load is 45 ft-kips, and the maximum moment for the service live load is 63 ft-kips (these moments occur at the same location on the beam and can therefore be combined). a. If load and resistance factor design is used, determine the maximum factored bending moment (required moment strength). What is the controlling AISC load combination? b. What is the required nominal moment strength for a resistance factor of 0.90? c. If allowable strength design is used, determine the required moment strength. What is the controlling AISC lead combination? d. What is the required nominal moment strength for a safety factor of 1.67?
