I am trying to solve the above example ( attachment).
Seismic analysis consist of EC 8, acceleration coeff.0.35, zone B and behavior coeff. 2 damping 5%
the modal analysis and deformations are correct, but the reactions for the seismic case do not correspond to the example.
I don't know where the mistake is?
You need to put the combination sign "1" (in your case) and then you gone have the right reactions.
Can you please be more specific?
Have you checked with EC 8 code book the way \ correctness of Sax calculations for given data for each mode?
EC8, Part 1, 188.8.131.52 Horizontal elastic response spectrum -> calculations of Se(T)
1. Case 2 is model case so N/A results are correct
2. These values are calculated by program. Not possible to change thm in Robot. Maybe in your program...
