Has anyone looked at the BCJ shear strength methods in C5-2025a?
Applying C5.78 (lightly reinforced) and C5.92/C5.95 (well reinforced exterior) to the same joint, C5.78 consistently gives higher capacity — meaning a well-reinforced joint assesses as weaker than an unreinforced one. Physically nonsensical.
C5 provides no explicit condition on when each method applies relative to the other, but even if you accept that they are not meant to be compared — the result still doesn’t make physical sense. A joint with more reinforcement should never give lower capacity. Has anyone else encountered this? or if i missed something?
