Using LRFD, determine the design shear strength of a W14x109 made from A992 steel.

Determine the magnitude of the largest shear force (consider both positive and negative peaks). Use a = 18 ft, b = 6 ft, and w = 10 kips/ft. The reaction forces for this beam are Ay = 80.00 kips and By = 160.00 kips.

Using ASD, determine the nominal flexural strength of a W16x45 beam made from A992 steel that has lateral support at 10-ft intervals. Assume Cb = 1.0.
