Figure D-9: Table For Capacity Spectrum<br />
• Step identifies the step number in the pushover curve.<br />
• Teff is the effective period at the associated step.<br />
• βeff is the effective damping at the associated step.<br />
• Sd(C) and Sa(C) define a point on the ADRS capacity curve for the associated step.<br />
• Sd(D) and Sa(D) define a point on the single demand spectrum (variable damping) curve<br />
for the associated step.<br />
• Alpha is the factor used in converting the base shear to spectral acceleration at the<br />
associated step.<br />
• PF*φ is the factor used in converting the displacement to spectral displacement at the<br />
associated step.<br />
