Using LRFD, determine the nominal flexural strength of a W14x53 beam made from A992 steel that has lateral support at 6-ft intervals. Assume Cb = 1.0.

Determine the magnitude of the largest shear force (consider both positive and negative peaks). Use a = 20 ft, b = 7 ft, and w = 6 kips/ft. The reaction forces for this beam are Ay = 52.65 kips and By = 109.35 kips.

Using LRFD, determine the nominal flexural strength of a W16x50 beam made from A992 steel that has lateral support at 5-ft intervals. Assume Cb = 1.0.

Determine the magnitude of the largest shear force (consider both positive and negative peaks). Use a = 22 ft, b = 8 ft, and w = 8 kips/ft. The reaction forces for this beam are Ay = 76.35 kips and By = 163.65 kips.

Determine the limiting laterally unbraced length for the limit state of yielding, Lp, for a W12x40 with a simple span of 4 ft if lateral bracing for the compression flanges is provided at the ends only. Use Fy = 85 ksi.

Мы ________ в Россию ка́ждое ле́то.  We travel (go by vehicle) to Russia every summer.

Determine the magnitude of the largest shear force (consider both positive and negative peaks). Use a = 21 ft, b = 7 ft, and w = 6 kips/ft. The reaction forces for this beam are Ay = 56.00 kips and By = 112.00 kips.

Determine the limiting laterally unbraced length for the limit state of inelastic lateral-torsional buckling, Lr, for a W6x20 with a simple span of 16 ft if lateral bracing for the compression flanges is provided at the ends only. Use Fy = 90 ksi.

Ви́ктор ________ в шко́лу, когда́ мы его́ уви́дели.  Victor was on his way to school, when we saw him.

Determine the limiting laterally unbraced length for the limit state of yielding, Lp, for a W12x40 with a simple span of 26 ft if lateral bracing for the compression flanges is provided at the ends only. Use Fy = 65 ksi.
