Good day,
Regarding the anchorage of positive moment reinforcement, aci318-11 states that u need to enter the support by 150mm and the bar diameter should be small in order to satisfy an equation ( section 12.11.3) (ld <Mn/Vu + la). This option is disregarded if the reinforcement is anchored with a standard hook beyond the center of the support.
Do u usually satisfy that condition or do u just anchor the bottom reinforcement using a standard hook ?
Same thing applies for the 2-way slabs.
in columns strips, bottom reinforcement should be anchored by a standard hook at the slab edge while in the middle strips, 150mm is enough. I think it is too complicated to be done and to verify on site so i ask for all the bottom reinforcement to be anchored by a standard hook.
what do u think ?
