I’m analyzing a hat composite section. In the analysis with HyperSizer the section has no radius. The bottom cap width is measured from corner to corner (intersection of web and bottom cap) with the assumption that the reinforcing 0 cap plies are running along the width of the bottom cap.
In reality the section will have a radius and the 0 plies of the bottom cap will drop before the radius. Therefore, the bottom cap stiffness is reduced based on how large the bottom cap to the web radius is.
Is HyperSizer taking any of the above mentioned into account during the analysis? Do I need to reduce the width of the bottom cap (artificially) to match the actual section’s EA & EI?
