problem solved. just in case, if someone wants to know:
for Romania, ag=0.16 G, reinf. concrete building, ductility factor 4.725 the starting value for design spectrum is 1.6 m/s2 at T=0, with 0.9 m/s2 between 0.07 and 0.07 seconds.
scale factor "1" for N m units
Can somebody help me with some values for the Scale factor in the definition of the response spectrum ? Especially for the definition of romanian p100 - 2006 seismic code (or EC8).
When defining a response function in etabs / sap2000 the values for the accelerations represent fractions of G...
