Design Loads for Buildings & Other Structures California. Building Code; 2013. Edition Other: AC428; Acceptance. Criteria for Modular'Framing Systems Used to. Support PV Modules, dated Effective November 1, 2012 by ICC -ES Aluminum Design Manual, 2010. Edition IronRidge Exhibit A The structure is a -simple column (pier) and beam (cross pipe) system. The piers & cross pipes are 3 inch ASTM A53 Grade B standard weight (schedule 40) steel pipes. The tops .of the' piers are connected in the .E -W direction by the cross pipes which cantilever .over and extend past. the end piers. The cross pipes are connected by proprietary IronRidge XR1000 Rails spanning . up and down the slope which cantilever overand extend past the top and bottom cross pipes. The solar' modules are attached to the rails with IronRidge clamps. There are typically. two rails per column of modules. Gravity loads are transferred to the piers and foundations by the rails and cross pipes acting as simple beams. For lateral loads the system is a cantilever structure. The effect of seismic loads (for all design categories A -F) have been determined to be less than the effect due to wind loads in all load conditions and combinations. The pier spacing in the N -S direction is 7'-6". The pier spacing in the E -W direction is 12'-6" and is determined by the structural design for the specified design criteria below. The 'governing criteria for the pier spacing is the cantilever capacity of the piers. The foundations shall be 12" diameter and shall have a depth below finished grade of 7'-0".

Taggart, Vice President Products Subject: Ground Mounting System Structural Analysis -4 Module Dear Sir: We have analyzed the subject ground mounted structure and determined that it is in compliance with the applicable sections of the following Reference Documents: EUTTE Codes: ASCE/SEI 7-10 Min. Design Loads for Buildings & Other Structures COUNTY .-California Building Code, 2013 Edition NOV 2 6----2014 Other: AC428, Acceptance Criteria for Modular Framing Systems Used to Support PV Modules, dated Effective November 1, 2012 by ICC -ES Aluminum Design Manual, 2010 Edition DEVELOPMENT IronRidge Exhibit A 'SERVICES The structure is a simple column (pier) and beam (cross pipe) system. The piers & cross pipes are ASTM A53 Grade B standard weight (schedule 40) steel pipes or structural equivalent, with minimum geometry and material properties of OD 3.5", wall thickness 0.216", and 35ksi yield strength for 3" pipe and OD 2.38", wall thickness 0.154", and 35ksi yield strength for 2" pipe. The tops of the piers are connected in the E -W direction by the cross pipes which cantilever over and extend past the end piers. The cross pipes are connected by proprietary IronRidge XR 1000 Rails spanning up and down the slope which cantilever over and extend past the top and bottom cross pipes. The solar modules are attached to the rails with IronRidge clamps. There are typically two rails per column of modules. Gravity loads are transferred to the piers and foundations by the rails and cross pipes acting as simple beams. For lateral loads the system is either a cantilever structure or, when diagonal braces are provided, a braced frame. The effect of seismic loads (for all design categories A -F) have been determined to be less than the effect due to wind loads in all load conditions and combinations. The pier spacing in the N -S direction is 7'-6". The pier spacing in the E -W direction is selected from load tables determined by the structural design for the specified slope, wind load, and snow Load. The governing criteria for the pier spacing is either the spanning capacity of the cross pipes or the cantilever capacity of the pier. Simplified Load Tables 1 A -F & 2A -F are included herein for reference. More comprehensive information covering all load combinations is available at the IronRidge website, IronRidge.com.

End cantilever span of pipe rails (max) = 0.40 x. adjacent interior span length 4. When installations occur on a grade, the design slope of the array shall be determined as the slope relative to level ground. Code required topographic effects have not been considered. Topographic (Wind) Factor = 1.0 (no topographic effects) 5. Dead Load (Weight) = 3 psf 6. Maximum PV Module Dimension = 78" To avoid potential problems from the effects of thermal expansion, a maximum total continuous cross pipe length of 100 ft is recommended. Foundation Requirements The foundation requirements for a cast -in-place drilled concrete pier system and for each soil class 2, 3, & 4 may be obtained from the tables below. The soil class is noted at the top of the tables. For each soil class Tables 3A -3F and 4A -4F are provided for the 2in and 3in systems respectively. These tables are based on the piers being installed at their maximum allowable spacing. For spacing values less than maximum and for loads cases with snow> 0 psf, the requirements can be determined by using the online Design Assistant at IronRidge.com. Starling Madison Lofquist, Inc.
