| fck |
This represents the characteristic strength of the concrete. |
| Mpl.Rd |
This represents the plastic resistance moment of the section with full shear connection (full composite action). |
| MRd |
This represents the plastic resistance moment of the section with partial shear connection (partial composite action). |
| C |
This represents the effective concrete flange force based on partial composite action. |
| PNA |
This represents the Plastic Neutral Axis of the composite section. |
| Pstud/PRd |
This represents the ratio of the actual shear in each shear connector and the shear resistance of a shear connector, and is used to determine the value of composite I to be used in the deflection calculations. |
