WebMar 16, 2016 · Shear areas have been obtained for a few different cross-sections. I-sections usually define their shear areas as equal to the product of the height of the section and the thickness of the web (assuming they fall under the thin-walled category). However, what would the shear area for these sections be (assuming thin-walled theory applies)? WebOct 21, 2014 · Shear Centers for a few other sections • Thin walled inverted T-section, the distribution of shear stress due to transverse shear will be as shown in Fig.11 . • The moment of this distributed stress about C is obviously zero.
