modifiers for wall
modifiers for wall
(OP)
hi all,
regarding the modifiers to apply to walls, I assign 0.7 to f22 for walls and then check the stresses using P/A + Mv/I to see if there is any tension area. if the tension stresses are higher than the modulus of rupture(generally in the upper stories where axial force is less) , 0.35 is assigned for f22 and drift(if any) is checked.
Any comments ?

For wind, it is iterative depending of the cracking state as described in previous posts.

when columns ask for much more reinf't at the higher story and this ratio decreases directly to the minimum the story below, do u add reinf't just at that story ?
