Notes: <br />1. The Design Response Spectrum is based on 2022 OSSC Section 1613. <br />2. The following parameters are based on the modified USGS 2014 maps provided <br /> in 2022 OSSC: <br />Site Class = D Damping = 5% <br />SS = 0.70 Fa = 1.24 SMS = 0.87 SDS = 0.58 <br />S1 = 0.40 Fv = 1.90 SM1 = 0.76 SD1 = 0.51 <br />3. SS and S1 values indicated in Note 2 are the mapped, risk-targeted maximum considered <br /> earthquake spectral acclerations for 2% probability of exceedence in 50 years. <br />4. Fa and Fv were established based on 2022 OSSC Tables 1613.2.3(1) and 1613.2.3(2) <br /> using the selected SS and S1 values. SDS and SD1 values include a 2/3 reduction on <br /> SMS and SM1 as discussed in 2022 OSSC Section 1613.2.4. <br />5. Site location is: Latitude 44.0463, Longitude -123.0810. <br />Project No.: 2251077 <br />Eugene, Oregon <br />FIGURE 3A <br />The Mark at Eugene <br />ASCE 7-16/2022 OSSC SITE RESPONSE SPECTRUM <br />0.0 <br />0.1 <br />0.2 <br />0.3 <br />0.4 <br />0.5 <br />0.6 <br />0.7 <br />0 0.5 1 1.5 2 2.5 3Spectral Acceleration, Sa(g)Period (seconds) <br />OSSC 2022 <br />Response Spectrum
