Live Load Reduction for Connections 3

[TidePoolJunkie]

Hi all,

What are engineers out there doing for long span situations where a girder is eligible for a live load reduction (floor live load, trib area>400sf--ASCE 7), but the trib area for the connection at either end of the girder is <400sf (ie 700sf for the girder, 350 sf for the connection).

Thanks,

Kyle

But I still say it's not logical to me

It may melt your brain, but this document should help a little in finding some logic. I'm still working through it myself. I grasp statistics pretty well in a qualitative sense, but the number crunching of statistics has always been a weak spot for me. (It wasn't until well after college that I came to realize why statistics is important, so I didn't give it its due attention during class...) So I'm finding it to be more challenging than it should be. It includes live load reduction reliability comparisons, among other things.

@phamENG that is mind melting alright but really cool reference thanks for sharing.
I find it amazing that these guys were chipping away at LRFD this long ago and we still haven't transitioned fully (I guess we can leave that for another thread).
