Block Shear Rupture Design Example
Worked block shear rupture calculation for a connection plate with two bolt lines per AISC 360-16 §J4.3. Demonstrates net shear area, net tension area, tension reduction factor U_bs = 0.5, and LRFD design strength.
Given Parameters
connection plate thickness
steel grade (ASTM A36)
bolt pattern
standard hole diameter
longitudinal pitch and transverse gauge
end and edge distances
factored tension force
Calculation Steps
1. Shear Plane Areas Agv and Anv
2. Net Tension Plane Area Ant
3. Tension Stress Uniformity Factor U_bs
4. Block Shear Nominal Strength Rn (AISC Eq. J4-5)
5. LRFD Design Strength phi Rn
Block Shear Design Strength
