Re: Sharing Holdowns @ Corners

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Bill,
 
Does not this requirement apply only to certain cases as listed in 1633.1?  Even under those conditions, however, the 100-30 method is not the only "correct" one, the SRSS may also be used.

The correct method is to use 100% of the uplift in one direction plus 30% of the uplift in the perpendicular direction and compare it to the 30%/100% case.

I don?t think you need to design for both overturning forces acting simultaneously.  That is not physically possible. 

I have always just sized one holdown for the largest of the two forces, and made sure the corner studs were nailed together adequately.

Yes it can be done.  Just make sure the hold down has enough capacity to support the uplift from both directions if applicable.

Subject: Sharing Holdowns @ Corners

 

Is it permissible to share a single holdown at a corner where 2 shear walls intersect?  I was thinking of configuring the corner studs to be nailed together as a built up post and using one holdown.  Is this commonly done?  Any specific recommendations of how to share a holdown?  I don?t find any details about this in anchor catalog.

 

Thanks.

 

Rich
