Is it permissible under IBC 2015/ACI 530-13 to use joint reinforcement to satisfy the horizontal reinforcement ratio of special masonry shearwalls? I see in the 7th ed of the Reinforced Masonry Engineering Handbook they show an example doing this but do address how this satisfied the requirement that horizontal shear reinforcement of special masonry shearwalls must be hooked around the last vertical bar...If you have the last grid of ladder joint reinforcement around this last cell have you provided the same/intent of hooking the bar per code? Also they speak to have the the first course be the first horizontally reinforced course or having this bar be in the footing instead; is the latter stragety addressed in the code
