JOB NO.: A0035-0164-221 <br />SUBJECT: LOAD COMPARISON <br />PROJECT: Jose Duenas Residence <br />Summary of Loads <br />Existing With PV Array <br />D [psf]17 19 <br />Lr [psf]20 0 <br />S [psf]0 0 <br />Maximum Gravity Loads: <br />Existing With PV Array <br />(D + Lr) / Cd [psf] 29 21 ASCE 7-16, Section 2.4.1 <br />(D + S) / Cd [psf] 19 21 ASCE 7-16, Section 2.4.1 <br />Maximum Gravity Load [psf]: 29 21 <br />Ratio Proposed Loading to Current Loading:72% OK <br />The gravity loads, and thus the stresses of the structural elements, in the area of the <br />solar array are either decreased or increased by no more than 5%. Therefore, the <br />requirements of Section 503.3 of the 2019 CEBC are met and the structure is permitted <br />to remain unaltered. <br />(Cd = Load Duration Factor = 0.9 for D, 1.15 for S, and 1.25 for Lr) <br />Page 7 of 8 <br />918 S Laurel <br />07/29/22
