Hi,

Is it possible to use force (as UDL) vs time data set to perform time history analysis in C II . If so please provide me with more info.

Thanks .

Time history in CAESAR II only addresses point loads, there is no direct input for a uniform distributed load (UDL) that changes with time.
You may want to try adding a string of point loads along a run to simulate your UDL. This might be sufficient for a smaller model. You may see a pattern that may allow you to develop shortcuts to simulating this load in larger systems.

thanks a lot for your reply .
I have another question. Do I get any advantage (using Time history analysis instead of static) for such problems involving large impact loads that last only few milli seconds as in case of wave slamming?

The magnitude that we see here can lead to high stresses (beyond the elastic limit).

I am treating it as an accident load and checking it against min (1.5 Sy or 2.4 Sh).

can any one state the advantage. Thanks.

Static evaluation will have you consider a Dynamic Load Factor (DLF). You can set this based on your expected mode of vibration that would be excited by the event. A time history analysis will basically do this for you. With such a short duration, the event will have the peak DLF at high frequencies- with little amplification of piping modes that show large structural response (deflection & bending). In my opinion.
