Final Structural Report <br />PROJECT NUMBER: AE230325 | PROJECT NAME: CPT HARBOR ANA <br />ACROS ENERGY | acrosenergy.com | 512.663.9058 | info@acrosenergy.com 5 / 23 <br /> <br />5. Total PV System Weight <br />The total PV system weight added to the roof of the building should be limited to the following value: <br />Maximum Total PV System Weight 182,600 lbs <br />The above weight is in accordance with the 2022 California Existing Building Code Sections 503.4: <br />Any existing lateral load-carrying structural element whose demand-capacity ratio with the addition <br />and/or alteration considered is not more than 10 percent greater than its demand-capacity ratio with the <br />addition and/or alteration ignored shall be permitted to remain unaltered. If the demand- capacity ratio <br />is increased by more than 10 percent, the subject structural element is checked against the applicable <br />Code criteria for new structures. <br /> <br />6. Concentrated Point Load Capacity and Attachment Strengths <br />Maximum Concentrated Downward Load <br />For concentrated loads spaced at 4.25ft over the 2x4 purlins, the concentrated downward loads imposed <br />to the existing structure from the racking support points should be limited to the following values: <br />For Dead Load Only 144 lbs <br /> For Dead Load + Wind Load 292 lbs <br />Attachment Strengths <br />Attachment strengths have been provided below for PanelClaw racking system with U-bracket. It is <br />essential to restrict the loads on the attachments to the following values. All fasteners must be at least 1 <br />inch embedded into sheathing for the design strengths to be applicable. <br /> <br />Attachment Type Fasteners <br />Attachment Strength <br />Uplift (lbs) Shear (lbs) <br />U-Anchor 2400/2600 8 - No. 14 340 170 <br />OMG PowerGrip Plus 8 - No. 14 340 170 <br />Facet 12 - No. 14 340 170 <br />
