A simply supported beam (B-2) supports a uniformly distributed load and is braced at five-foot intervals in addition to a composite slab that is secured to the compression flange of the beam via shear studs. Assume that the beam is made of ASTM A992 grade with Fy = 50 ksi. Select the lightest W shape to safely support the following loads: DL = 225 psf LL = 150 psf Beams are spaced at 10' o.c. 8.25*: A simply supported beam...
Steel foot bridge. The main beams are W10X12 A36 steel. Each beam are 36 feet long. Each beam is to support decking 18 in wide for the length of the beam (36 feet). Deck material places a 50 pounds per sq ft distributed load on the beam. In the center of the beam needs to support a 1200 lb point load. What are the loads on the beam and the safety factor?
Problem 2: Point loads A beam is loaded with a distributed load that has a total integrated magnitude f at its center. The load is uniformly distributed between -al< x<aL so that the force per unit length is f/2aL as shown in the figure below. o is a unitless number between zero and one. The beam has a Young's modulus E and a known moment of inertia I about its neutral axis.

Question 1 (6.7 points) AW12 x 50 steel beam is used as a simply supported beam on span of 24 feet. The beam supports a uniformly distributed load of 1000 lb/ft. Calculate the maximum bending stress. a) 9,560 psi Ob) 11,280 psi Oc) 13,460 psi d) none of the above Question 2 (6.7 points) Determine the number of 2 x 12's that need to be nailed together to build a beam that would support a uniform load of 500 lb/ft...
A W shape is to be used for a uniformly loaded simple beam carrying a total dead load of 22 kips and a total live load of 50 kips on a 30-ft span. Select the lightest weight shape for unbraced lengths of (2) 10 ft, and (2) 15 ft.
Chapter 5, Problem 5/099 The load per foot of beam length varies as shown. For x = 14 ft, the unit load is 447 lb/ft. At x = 0, the load is increasing at the rate of 56 lb/ft per foot. Calculate the support reactions at A and B. The reactions are positive if upward, negative if downward. w = kqx - kg x2 - - D - - 7 14' Answers RA Rp =
