A beam in Figure la is simply supported at A and C and subject to uniformly distributed load of 300 N/m with a moment of magnitude 2700 Nm. Express the shear and moment in terms of x and then sketch the shear and moment diagrams for the beam. 1.
A square wood platform of side-length ? = 2.4 m rests on masonry walls. The deck of the platform is constructed of 4 cm thick planks supported on two beams which are 2.4 m long. The beams have a width of 100 mm and height of 150 mm and are supported at their ends by the walls. The structure is designed to support a uniformly distributed load, ?? (kN/m2), acting over the entire top surface of the platform. The tensile...
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...

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...
