You can check 8+ pages plastic neutral axis of composite section answer in Doc format. Y C Figure 30. The nominal moment capacity M n is taken as the internal moment that results from the forces on the section components. In the following deduction figure 10 the plastic neutral axis is located close to the top. Check also: axis and plastic neutral axis of composite section If the depth of the compressive stress block a required to balance out the full tension of the steel exceeds the thickness of the slab t s then there is not enough concrete to develop the full tensile strength of the steel and the PNA.
STRESS CONCENTRATIONS 46 47 Slide No. Figure 30 shows the fictitious distribution of normal stresses on the section.

This is not the case for composite beams and is one of the main difficulties in solving for the bending stress.
1For normal composite beams in case of sagging moments and a high plastic neutral axis the real moment resistance is considerably greater than the plastic design moment. If a is within steel section the part below the Plastic Neutral Axis PNA is in tension and everything above the PNA is in compression the steel and the concrete 4. Step II Estimate the position of the neutral axis Y using Y. Wouldnt the plastic neutral axis be located in the slab if c ts where c abeta1. The same concept can be used in case of composite beams also provided the steal area. The composite beam design in negative moment regions adopted was first proposed in Johnson 1975 and refined in the present study.
