SUSTAINED LIVE LOAD QUESTION

SUSTAINED LIVE LOAD QUESTION

SUSTAINED LIVE LOAD QUESTION

(OP)
CAN SOMEBODY EXPLAIN TO ME THE REASON OF USING A TYPICAL 30% SUSTAINED LIVE LOAD USED IN COMPUTATION OF CONCRETE BEAM DEFLECTIONS?

THANKS. =)

RE: SUSTAINED LIVE LOAD QUESTION

Some component of the live load is generally sustained in nature and therefore would contribute to creep induced member deformation. 30% is an estimate of that component. You can modify the percentage if you're confident that an alternate value is more appropriate.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Thank you very much for the response. =)
