Impact Loading
(OP)
Folks,
Should a 1.6 multiplier for live load be used in conjunction with the 2.0 multiplier for impact loading resulting in a 3.2 multiplier on the service load?

RE: Impact Loading
Yes. The 2.0 multiplyer only accounts for the instantaneous load created when stopping a moving mass.

You don't give any context for your question, but be aware that the 2.0 factor is usually used to allow for the effect of SUDDENLY APPLIED loads, as opposed to IMPACT loads.

A suddenly applied load is likely much less than a load stopped "instantaneously" from 8 fps. Unless the stop crumples, than the load will be less. But your stop will be destroyed.
