Re: what the meaning of"critical shear wall"?!
Hİ Ammer
This image shows critical height(Hcr) of shearwall that is applied the head zones. Program creates automaticly head zones throughout that height according to Turkish Seicmic Code
Hcr >= lw
Hcr>= Hw/6
lw= length of shearwall on plan
Hw=Total shearwall height along the structural height
It's better that not creating door space on this critical height.
Please check this your previous question and my answer as well.
