Hi guys,
I' m trying to make a seismic analysis, using the response spectrum (EC8) from the "load item" list.
In the second phase I' m define one spectrum in x and y direction (direction parameters 1 and 0,3), specifying the masses (selfweight, live and dead loads in x and y) in the reference loads definitions
Unfortunatelly i' m not getting the right results.
Anyone know how to procede to make a seismic analysis following the EC8?
Thanks
For response spectrum in X+ and X- direction, the Mx diagrams are the same.
Even in Y direction I have the same condition.
The responses obtained from the Response Spectrum analysis are absolute unsigned quantities. If you want to see signed bending moment diagrams, you can use either Dominant or Signed option in the Response Spectrum Load Case settings.
