Check Horizontal Block Shear
Using AISC 15th Ed. Equation J4-5
Block Shear = {(phi) * ((0.6 * Fu * Anv) + (Ubs * Fu * Ant))} <= {(phi) * ((0.6 * Fy * Agv) + (Ubs * Fu * Ant))}
Block 1:
Gross Shear Length = 2 * (Lconn + Levgus) = 2 * (21.00 + 1.00) = 44.00 in.
Net Shear Length = Gross Shear Length - 2 * ((#rows - 0.5) * (hwang + 1/16)) = 44.00 - 2 * ((8 - 0.5) * (0.81 + 0.06)) = 30.88 in.
Gross Tension Length = (#cols - 1) * g2 = (2 - 1) * 2.50 = 2.50 in.
Net Tension Length = Gross Tension Length - (#col - 1) * (hhang + 1/16) = 2.50 - (2 - 1) * (0.81 + 0.06) = 1.62 in.
1. (phi) * [material thickness] * ((0.60 * Fugus* [net shear length]) + (Ubs * Fugus * [net tension length]))
= 0.75 * 0.31 * ((0.60 * 65.00 * 30.88) + (1.00 * 65.00 * 1.62)) = 306.98 kips
2. (phi) * [material thickness] * ((0.60 * Fygus * [gross shear length]) + (Ubs * Fugus * [net tension length]))
= 0.75 * 0.31 * ((0.60 * 50.00 * 44.00) + (1.00 * 65.00 * 1.62)) = 334.14 kips
Block Shear = 306.98 kips
306.98 kips >= Pbrace uplt = 300.00 kips (OK)
Here what we have now is "hwang" and "hhang" - however it should be “hwgus” and “hhgus”

EngineeredGroups: Fix VB grouping process - Vertical Brace connections are typically unique. We will not group them with other VB connections with Engineered Groups.
