No, I was not specific to BS 6399!
For example if someone is carrying out a forced vibration etc. analysis using sinusoidal force function then how can he interpret or process the results to find out a factor which he can use to complete a separate pseudo-static analysis of the the same structural system under static force (amplified using the factor previously calculated)!?? I can appreciate one can combine the former analysis results using SRSS etc and can directly compare with the allowable values but I would like to understand the approachl!!
I hope I made myself clear here!!
Thanks.
