6 FAQs about [Compressive strength of photovoltaic bracket]
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.
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.
What is a supporting cable structure for PV modules?
Czaloun (2018) proposed a supporting cable structure for PV modules, which reduces the foundation to only four columns and four fundaments. These systems have the advantages of light weight, strong bearing capacity, large span, low cost, less steel consumption and applicability to complex terrain.
What are the structural static characteristics of a new PV system?
The structural static characteristics of the new PV system under self-weight, static wind load, snow load and their combination effect are further studied according to the Chinese design codes (Load Code For The Design Of Building Structures GB 2009-2012 and Code For Design Of Photovoltaic Power Station GB 50797-2012).
What are the characteristics of a new cable-supported PV system?
Dynamic characteristics As the new cable-supported PV system has the characteristics of a smaller mass and greater flexibility, vibration suppression is one of the key factors of the new structures. Therefore, the mode shapes and modal frequencies are important parameters in the structural design of the new cable-supported PV system.
What is the inflection point of a cable-supported PV system?
When the upward vertical displacement is less than 0.0639 m, the force first counteracts the self-weight of the cables and PV modules. Therefore, there is an inflection point at 0.0639 m. For the new cable-supported PV system, the lateral stiffness is much higher than the vertical stiffness.
