The Basics of Transform Section Method for Composite Beams!

Question 6-129: The beam is made from three types of plastic that are identified and have the moduli of elasticity shown in the figure. Determine the maximum bending stress in the PVC.

If you have a concrete slab on top of a steel beam which one do you transform

[@simple_civil]

You can do either, but typically you convert the concrete to steel. It is much easier as the slab is a simple rectangle, while the beam has multiple individual rectangular sections.
Additionally, for analysis, you would take the tributary area of that slab above the beam, and use that as your untransformed b value.
hope that helps!
