Connection Screen — Block Shear Concept Check
Block Shear Concept Check — a screening-level structural check.
Block shear is the failure mode that rips the corner out of a coped beam web — a block of material tearing along the bolt lines. It governs coped ends and gusset edges more often than bolt strength does; this simplified check flags when the full calculation is mandatory.
Formula
Note: Screening only — NOT a connection design. All capacities must be verified by a licensed engineer against the governing code, including the limit states this simplified check omits.

About Connection Screen — Block Shear Concept Check
Connection Screen — Block Shear Concept Check computes the governing relationship φRn = 0.75 × min(0.6FyAgv + FuAnt, 0.6FuAnv + FuAnt) — simplified live as you type. Block shear is the failure mode that rips the corner out of a coped beam web — a block of material tearing along the bolt lines. It governs coped ends and gusset edges more often than bolt strength does; this simplified check flags when the full calculation is mandatory. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Connection Screen — Block Shear Concept Check
- 1Enter your values — Gross shear area, Net tension area, Yield Fy, Tensile Fu (sensible defaults are pre-filled).
- 2Read the live results: Design capacity (φ=0.75).
- 3Check the "with your numbers" line to see φRn = 0.75 × min(0.6FyAgv + FuAnt, 0.6FuAnv + FuAnt) — simplified substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Connection Screen — Block Shear Concept Check?
