ACI 530-05 Slender walls, h/t

[ARLORD]

What is the limit for a slender masonry wall, ratio h/t. ACI 530-05 Section 3.3.5.4 refers the slenderness ratio exceeding 30, but I do not see where that code defines the ratio or the limit for a wall being slender. I also looked in IBC.

Unless they have recently added it, ACI 530 does not have a slender wall method for wall design like UBC had.

 

[ARLORD]

Yes, I am just trying to find how to determine when a wall is considered slender, at what h/t ratio. Does the code not specify this.

 

[haynewp]

ACI 530 does not directly specify this, which makes sense since it does not give a different procedure for slender walls.

 

[haynewp]

The higher slenderness is addressed implicitly by the section you referenced.
