  • Concrete Basics

    the concrete across the bottom of the beam must crack first. We assume that the compressive stress in the con-crete is carried uniformly across the top portion of the concrete—another oversimplification, but close enough for most designs. To get the beam to behave the way we want it to, we adjust the amount of concrete (size of the beam)
