Misc. Parking Structure

[gdubb08]

I am designing a 'height restrictor' for lack of better terms. Attached is a photo of what is proposed. My question is what sort of load to throw at the structure. It is a replacement for one that was hit.... I have designed vehicle barriers (ground mounted concrete or cable) in the past and seem to remember using 5000# as my design load but don't remember where that # came from. Is there a design refence that could be suggested?

Thx in advance,


GW

Do you want an actual restrictor, or just something that will not damage the vehicle and caution them that it is too high?

Even if you raise it a few feet and dangle something non-destructive from it a semi (I'm being extreme on purpose) could come through and still hit it.

I just found section 1607.7.3 of 2009 IBC calling for 6,000 so my memory was a bit off.
