Thrust area

The shear area is a calculated reduction in the cross-sectional area of a body, which is often used in civil engineering. ${\displaystyle A_{S}}$ ${\displaystyle A}$

${\displaystyle A_{S}=\kappa \cdot A}$

The correction factor takes into account the non-uniform distribution of the shear stress across the cross-section . ${\displaystyle \kappa }$ ${\displaystyle \tau }$

For example, the correction factor can be calculated for a rectangular cross-section . In the case of a double T-beam , the web area is assumed to be approximately. ${\displaystyle \kappa ={\frac {5}{6}}}$ ${\displaystyle A_{S}}$
