Calculation method of photovoltaic support load-bearing capacity

What factors affect the bearing capacity of new cable-supported photovoltaic modules?

The pretension and diameter of the cables are the most important factors of the ultimate bearing capacity of the new cable-supported PV system, while the tilt angle and row spacing have little effect on the mechanical characteristics of the new type of cable-supported photovoltaic modules.

How does torsion stiffness affect load bearing capacity of PV system?

The increase of torsion stiffness when the torsion displacement rises benefits the stability of the new PV system. The load bearing capacity of the PV system is discussed under self-weight, static wind load, snow load, and their combination.

How does cable spacing affect load bearing capacity?

When the row spacing increases from 1.24 m to 2.98 m, the bearing capacity slowly decreases by 0.72%. When the tilt angle increases from 0° to 30°, the bearing capacity increases by 6.16%. However, the initial force of cables and cable diameter obviously affects the load bearing capacity of the structure.

Does row spacing and tilt angle affect load bearing capacity?

The results show that row spacing and tilt angle has little influence on the load bearing capacity of the structure. When the row spacing increases from 1.24 m to 2.98 m, the bearing capacity slowly decreases by 0.72%. When the tilt angle increases from 0° to 30°, the bearing capacity increases by 6.16%.

What are the characteristics of a cable-supported photovoltaic system?

Long span, light weight, strong load capacity, and adaptability to complex terrains. The nonlinear stiffness of the new cable-supported photovoltaic system is revealed. The failure mode of the new structure is discussed in detail. Dynamic characteristics and bearing capacity of the new structure are investigated.

How does cable force affect bearing capacity?

When the initial cable force increases from 10 kN to 50 kN, the bearing capacity decrease by 14%. When the diameter of the cable increases from (14,16) mm to (24,32) mm, the bearing capacity increases by 272%. Table 11. The ultimate static wind load bearing capacity (Case 180°) of the new structure under different structural parameters. 6.
