Calculate Block Shear Rupture Strength of a Member:

Calculation:

Designer/Checker:

Input:

Metric Units

(Note: All input Metric units are converted to English units for the equations below and then the output English units are converted back to Metric)

AISC J4.3:

The following is for calculating block shear rupture strength in a member. Block shear is when shear and tension both are acting on a member.

ASD

LRFD

Uniform Tension (Ubs = 1.0)

Nonuniform Tension (Ubs = 0.5)

Net area of the member in tension (Ant- sq in or sq mm)

Steel tensile strength (Fu - ksi or MPa)

Gross area of the member in shear (Agv - sq in or sq mm)

Net area of the member in shear (Anv - sq in or sq mm)

Steel yield strength (fy - ksi or MPa)

Output:

Nominal tensile yield strength, Pn =

Maximum tensile yield strength, Pu =
