Re: H/b ratio for Low shear walls

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I understand now. I tend to agree since this is the premise that I have taken 
with proprietary shear walls. I simply design for their maximum capacity to 
resist uplift and know their maximum deflection. I also do not vary widths in 
each line of shear on the same panels.
The only issue that remains is what is the relative stiffness of each line of 
shear compared to adjacent lines of shear.

<< Dennis,
 You probably did not understand what I meant. What I was saying is that if 
 the h/d limit has been reduced to 2 to limit the excessive deflection of 
 shear panels why bother with a deflection check? OR, if we limit the 
 deflection of a shear panel to the allowable story drift, why bother with a 
 h/d ratio? Obviously, a 3.5/1 ratio shear panel won't meet the drift 
 limitation when calculated for maximum allowable shear, so it is 
 automatically discounted as a shear resisting element. Wow, here's another 
 question to throw at the list members. What if you have a wall panel with a 
 h/d ratio exceeding 2 along a line of other panels meeting the h/d ratio? Do 
 you a). sheath it and add its stiffness to the line, or b) you disregard it 
 and face the consequences of a lawsuit claiming your design of the shear 
 did not account for the inherent stiffness of the finish material on that 
 discounted panel that contributed to absorbing more diaphragm shear along 
 same shear line? Pretty neat huh!
