Problem 2: the most economical (lightest) W shape to support a uniformly distributed load of 4k/ft...
Please refer AISC 15th edition 2. Select the lightest W shape to carry a uniformly distributed dead load of 0.5 kips/ft and a live load of 1.0 kips/ft on a simply supported span of 42 ft. Adequate lateral support is provided. The live load deflection is limited to 360, Use A572 Grade 50 steel and LRFD. (credit weight 30)

16.6a) A simply supported beam is to span 15 ft. It will support a uniformly distributed load of 2 kips/ft over the full span and a concentrated load of 60 kips at mid-span. What is the required plastic section modulus Zx? (Include self-weight) 16.6b) A simply supported beam is to span 15 ft. It will support a uniformly distributed load of 2 kips/ft over the full span and a concentrated load of 60 kips at mid-span. Deflection is not to...
Select the lightest W shape to support a uniformly distributed load of 80 kN/m and concentrated loads of 26kN located 4.5 m from the end of the beam. The beam is 16 m, Deflection is not to exceed span/280.
A steel I-beam with a span of 20 feet will support both a concentrated load of 15 kips at the beam center and a uniformly distributed load of 2 kips/ft along the entire beam length. The steel beam is Grade 50 (Fy= 50,000 psi). i) Calculate for the lightest W-shape section that will safely carry the load, with the depth not to exceed 17 inches. Provide sketches. ii) The analysis is to include (a) bending strength, (b) shear strength, and...
Select the lightest W shape for the loading below. All loads are dead loads and the 2 k/ft includes th beam weight. The steel is A992, the compression flange is supported at the ends and at the concentrated load and C 1.0. The maximum service load deflection cannot exceed 1/1000 of the span. Design for moment and check shear and deflection. Identify what zone the beam is in and check that it does not exceed zone 1 maximum strength. 13...
Problem 7.5 of your textbook (Haldar & Mahadevan): A simply supported beam of span L 360 inches is loaded by a uniformly distributed load w kip/in. and a concentrated kip applied at the midspan. The maximum deflection of the beam at the midspan can be calculated as: mar- 384 EI 48 E A beam with El 63.51 x 106 kip-in.2 Is selected to carry the load. Both w and P are statistically independent RVs with mean values estimated to be...
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.
A simply supported wood beam with a span of L = 16 ft supports a uniformly distributed load of w0 = 305 lb/ft. The allowable bending stress of the wood is 1.30 ksi. If the aspect ratio of the solid rectangular wood beam is specified as h/b = 1.75, calculate the minimum width b that can be used for the beam. A simply supported wood beam with a span of L = 16 ft supports a uniformly distributed load of...
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...
