49. A 32 ft simple span beam carries a uniform dead load of 2.4 k/ft plus its self-weight and a uniform live load of 3.0 k/ft. The beam is laterally supported at the supports only. Determine the minimum-weight W-shape to carry the load using A992 steel. Use the correct Ch, check shear, and limit live load deflection to 1/360 of span. Design by (a) LRFD and (b) ASD.

**Problem 49: Beam Design using A992 Steel**

A 32-foot simple span beam carries a uniform dead load of 2.4 kips per foot (k/ft) plus its self-weight, and a uniform live load of 3.0 k/ft. The beam is laterally supported only at the supports. Determine the minimum-weight W-shape to carry the load using A992 steel. Use the correct bending coefficient (\(C_b\)), check shear, and limit the live load deflection to 1/360 of the span. Design the beam using:

(a) Load and Resistance Factor Design (LRFD)

(b) Allowable Stress Design (ASD)
