Hi,
I have 2 questions:
1. If in the input for RSA we have Structural ductility, Structural performance, Importance factor then I presume scale X and Y shall be calculated automatically? So Scale x and y are really for 0.85 correction factor (correlation between dynamic and static shear)?
2. If I insert Scale X,Y=1 then I get excessive base shear forces (much higher than static) and still very small Mx and My values at the base (much lower than static). When I adjusted scale to be I/R (we don't have it in Australian standard but used it from ASCE as 1/4 for my building) - then I'm getting comparable base shear result to static analysis but still very low value for Mx and My.
Please advise
