QUESTION 11. A W12 x 65 of A572 Grade 60 (Fy = 60 ksi) steel is used as a compression member. It is 26 feet long, pinned at each end, and has additional support in the weak direction ata point 12 feet from the top. Using LRFD, can this member resist a service dead load of 180 kips and a service live load of 320 kips?2. A simply supported beam is subjected to a uniform service dead load of 1.0 kips/ft (including the weight of the beam), a uniform service live load of 2.5 kips/ft, and aconcentrated service dead load of 45 kips. The beam is 40 feet long, and the concentrated load is located 15 feet from the left end. The beam has continuous lateral support,and A572 Grade 50 steel is used. Is a W30 x 116 adequate? Use LRFD3. The cantilever beam shown in the figure is a W10 x 77 of A992 steel (Fy = 50 ksi). There is no lateral support other than at the fixed end. Use an unbraced length equal to thespan length and determine whether the beam is adequate in shear. The uniform load is a service dead load that includes the beam weight, and the concentrated load is aservice live load.
