Beams

In structural engineering, a beam is a component made of a variety of materials (including steel alloys, and wood) that can resist loads applied laterally to the beam axis. Members, elements, rafters, shafts, and purlins are all terms used to describe beams.

Question

10-19. Design a beam for a 24-ft simple span to support the working uniform loads of
3.0 k/ft. The maximum per-

missible total load deflection under working loads is 1/360 of the span. Use 50 ksi
steel and consider moment, shear, and deflection. The beam is to be braced laterally
at its ends and midspan only. Determine C. (Ans. W24 x 62 LRFD and ASD)

The beam shown below is subjected to a uniform live load, ωL = 1k/ft. In addition, the beam must resist a superimposed dead load, ωD.S = 0.8k/ft as well as its self-weight. The concrete strength is 6,000 psi and the steel is Grade 60. The beam is not in contact with the ground or exposed to weather (hint: cover). Calculate the nominal and design shear strengths of the beam section. Is the beam shear design adequate? If so, redesign the beam to make the design more economical. If not, redesign the beam for shear to ensure the design is adequate per ACI 318-19 standards. . The beam shown below is subjected to a uniform live load, ωL = 1k/ft.
