As I refer to Application Examples U.k. No 11 Response spectrum analysis of a frame.
The response spectrum was define as below:
SPECTRUM CQC X 1.0 ACC DAMP 0.05 SCALE 9.806
0.03 1.00 ; 0.05 1.35
0.1 1.95 ; 0.2 2.80
0.5 2.80 ; 1.0 1.60
Notes: The UNIT applied is in METER KNS. The units for acceleration supposed to be in m/s2
However in the result page indicate the acceleration in the unit ofG instead within the same decimal point as in the input values.
As 1 g=9.806m/s2, why the units in g are not divided by that value of 9.806 in the unit of G?
MODE ACCELERATION-G DAMPING
---- -------------- -------
1 2.74136 0.05000
2 1.36735 0.05000
Wondering how the scale factor of 9.806 being applied within the analysis. In this case the total base shear would be 9.806 time more than the expected value.
Can anyone helps to explain this.
