Can you help me with time history load, I already finish the time history loading and run analysis using perform anlysis
and then finish the design and displacement check, all members passed.
1. My question, Is my input for time history load correct?
2. Do I use perform anlaysis or non-linear or steady state etc?
3. Can i assume my structure subject to harmonic load because the structure is on top of turbine table thus using time history load is appropriate?
4. For the stress and displacement check of the member thus my results ok or do I need to generate load cases just like RSA wherein you need generate IMR load cases?
5. Regarding mass participation I only achieve 74% in y direction, how to increase, can I use cut-off mode?
6. Do i disregard the warning *WARNING- APPLIED SELFWEIGHT IS MORE THAN TOTAL WEIGHT OF ALL ?
7. What is the relationship between mode shape and deflection?
