Photovoltaic support greenhouse frame

What is a steel frame solar greenhouse?

With the development of the theory of active heat storage and release, a whole steel frame solar greenhouse has been proposed in recent years 16. This greenhouse structure is composed of a south roof, a north roof and columns. In this type of greenhouse, walls are replaced by columns.

Are whole steel frame greenhouses safe under wind loads?

With the characteristics of large flexibility and small mass, whole steel frame steel greenhouses are sensitive to wind loads. However, studies on the safety of whole steel frame steel greenhouses under wind loads are still limited. In this study, a 10 m span whole steel frame solar greenhouse was taken as the research objective.

Does a solar greenhouse include plastic film?

For the solar greenhouse covered by plastic film, the load acting on the plastic film is redistributed to the structural frame 21. Therefore, the model includes all steel frames, but does not include the plastic film. All the frame structures of the greenhouse are simulated by BEAM188 element.

Are flexible/lightweight PV modules a good choice for buildings & greenhouses?

A closer look at the literature on PV shows that there is a dearth of studies which place emphasis on PVs with lightweight BOS systems, highlighting the importance of flexible/lightweight PV modules for buildings and greenhouses.

Does plastic film affect structure safety of solar greenhouse under wind loads?

This study investigated the dynamic responses of whole steel frame solar greenhouse under wind loads. However, the effects of plastic film on the structure safety of greenhouse under wind loads does not consider. In reality, the plastic film may be failed before the skeleton structure.

What is the bending stress of a steel frame solar greenhouse?

The results are as follows: (1) Under wind loads, the whole steel frame solar greenhouse mainly bears bending stress, and the axial pressure stress is relatively small. The maximum bending stress occurs at the end of south roof. The maximum bending stress is lower than the yield strength of the material.
