Calculate Notched Bending Member Shear Strength

The following is for calculating shear strength of circular or rectangular bending member notched on the tension face.

Reference design value for shear (Fv)

*Cross section area of member at notch (An)

Depth of unnotched bending member (d)

Depth of member remaining at the notch (dn)

Load duration factor (Cd)

Wet service factor (Cm)

Temperature factor (Ct)

Incising factor (Ci)

Time effect factor (TEF)

Result

ASD shear strength, V

lbs

LRFD shear strength, V

lbs

Fv - Reference design value for shear
An - *Cross section area of member at notch
d - Depth of unnotched bending member
dn - Depth of member remaining at the notch
Cd - Load duration factor
Cm - Wet service factor
Ct - Temperature factor
Ci - Incising factor
TEF - Time effect factor
*For rectangular member, An = bdn
V(ASD) - shear strength
V(LRFD) - shear strength
