Solar Mounting Structure: Structural Design Concept Report 09/03/2564

The document provides design criteria and load calculations for a steel structure solar mounting system. It specifies standards that will be followed (AISC 360-10), materials that will be used (A572 Grade Gr.50 steel, ISO grade 8.8 bolts and nuts), and load cases to consider including dead load of panels/frames, live load of 30kg/m2, and wind loads calculated according to DPT 1311-50 standard with a basic wind speed of 25m/s. Load calculations are summarized including material properties, dead loads, imposed live load, and wind loads in the x, y, and z directions according to various standards. Results of the structural analysis like deformation, axial/shear/

Dead Load + Weight of Equipment


Weight of PV Module (DIM: 2279x1134x35mm) = 29 kg

Weight of Steel Frame Support Shall Be Included Automatically by Software

Impose Load
Live load (Roof Structure) = 30 kg/m2

Wind Load to PV Module and Steel Frame Structure (In Accordance with DPT 1311-50 Standard)
Maximum Basic Wind Speed as per DPT 1311-50 Annex A Vs = 25 m/s

Importance Factor Iw = 1

Reference Velocity Pressure q = 0.0637*Vs2 = 39.82 kg/m2

Exposure Factor Ce = 1.22

Gust Effect Factor and Equivalent Static Wind Pressure Cg*Cp = -2 (Annex B)

Equivalent Static Wind Pressure p = Iw*q*Ce*Cg*Cp = 97.16 kg/m2

z= 96.79 kg/m2
