1615.1 General procedure for determining maximum considered earthquake and design spectral response accelerations.
1 Ground motion accelerations, represented by response spectra and coefficients derived from these spectra, shall be determined in accordance with the general procedure of Section 1615.1, or the site-specific procedure of Section 1615.2. The site-specific procedure of Section 1615.2 shall be used for structures on sites classified as Site Class F, in accordance with Section 1615.1.1.
The mapped maximum considered earthquake spectral response acceleration at short periods (SS) is 0.265 and at 1-second period (S1) is 0.086.
The site class shall be determined in accordance with Section 1615.1.1. The maximum considered earthquake spectral response accelerations at short period and 1-second period adjusted for site class effects, SMS and SM1, shall be determined in accordance with Section 1615.1.2. The design spectral response accelerations at short period, SDS, and at 1-second period, SD1, shall be determined in accordance with Section 1615.1.3. The general response spectrum shall be determined in accordance with Section 1615.1.4.
