• See Section 2.424.
• Response parameter is pseudo-acceleration for 5% damping.
• Compute percentage decrease in σ², τ² and ϕ² by using SCPs over base model using no SCPs. Find V _s,30 is best SCP for T < 0.6s and f₀ and H₈₀₀ are better at long periods. Find V _s,30-H₈₀₀ and f₀-slope are best SCP pairs.
