Live load on chain link fence
Live load on chain link fence
(OP)
In AASHTO LRFD Section 13.8.2:
"The design load for the chain link or metal fabric fence shall be 0.015 ksf acting normal to the entire surface"
How was this load derived? It doesn't make sense to apply it to the entire surface no matter what height of the fence is. (For example, 10 ft high chain link fence over the bridge). Live load is live load. No matter what type of the fence is, the total applied live load should be simillar, correct? Should 0.2+0.05L be the maxium live load for the chain link fence post design?

RE: Live load on chain link fence
I've never heard of anyone designing a fence on a bridge, except on occasion the anchorage.
0.015 ksf? Who knows where it came from, but it seems reasonable. For example, elevator capacity assumes (at least it used to) an average weight per person of 150#. Roughly, there's the 15 psf (body surface area).

I've seen plenty of fences on bridges - tends to cut down on suicides and rock throwing..

Why does AASHTO do things a certain way? Because they've always done it that way.
