How to Calculate Capacity Spectrum?
Capacity Spectrum calculator uses Capacity Spectrum = (32*Spacing of Secondary Members*Length of Secondary Member^4)/(10^7*Moment of Inertia of Secondary Member) to calculate the Capacity Spectrum, The Capacity Spectrum formula is defined as the capacity curve transformed from shear force vs. roof displacement coordinates into spectral acceleration vs. spectral displacement coordinates. Capacity Spectrum is denoted by Cs symbol.
How to calculate Capacity Spectrum using this online calculator? To use this online calculator for Capacity Spectrum, enter Spacing of Secondary Members (S), Length of Secondary Member (Ls) & Moment of Inertia of Secondary Member (Is) and hit the calculate button. Here is how the Capacity Spectrum calculation can be explained with given input values -> 5.555556 = (32*2.5*0.5^4)/(10^7*9E-08).
