Dear All,
I have modelled and analysed a staad model with response spectrum analysis and the scale factor i have matched still im getting this. some one please clarify regarding this
NOTE : THE BASE SHEAR (VB) FROM RESPONSE SPECTRUM IS LESS THAN THE BASE SHEAR (Vb) CALCULATED USING EMPIRICAL FORMULA FOR FUNDAMENTAL TIME PERIOD. MULTIPLYING FACTOR (Vb/VB) ACCORDING TO 7.7.3a IS 1.0000
