NCMA TEK 14-4b has this equation for the maximum reinforcement ratio in CMU shearwalls:
I'm hoping one of you can help me understand how this equation isn't blowing up and going to infinity. The way I'm understanding it, that equation is dividing by 0 once my steel reinforcement reaches it's yield limit. (Which in a special wall is pretty damn quick, e.g. the intent of the alpha factor...)
I've found the same equation in ACI 530 (TMS 402), so I'm faaaairly certain it's not a typo. But I haven't found any evidence online of people screaming about an error, so I'm erring on the side of myself just not understanding the correct intent.
