Concept explainers
A beam must be designed to the following specifications:
• Span length = 35 ft
• Beam spacing = 10 ft
• 2-in. deck with 3 in. of lightweight concrete fill (
• Construction load = 20 psf
• Partition load = 20 psf
• Miscellaneous dead load = 10 psf
• Live load = 80 psf
•
Assume continuous lateral support and use LRFD.
a. Design a noncomposite beam. Compute the total deflection (there is no limit to be checked).
b. Design a composite beam and specify the size and number of stud anchors required. Assume one stud at each beam location. Compute the maximum total deflection as follows:
1. Use the transformed section.
2. Use the lower-bound moment of inertia.
