The third-generation Liaoshen solar greenhouse, which is widely used in the Liaoning Province, has a high rate of land utilization. This solar greenhouse is selected in the present research. Greenhouse span is. In this research, we determined the effect of the pipe shape and size on the greenhouse. The structural performances are investigated by finite element method based on the ANSYS 18.0 software. In this research, we have employed the equilibrium equat. The Beam 188 is a 3-D 2-node beam element based on the Timoshenko beam theory which includes shear-deformation effects, and is suitable for analyzing slender to moderately stu. The tie bars are fixed on the skeleton by buckles, which can be regarded as rigid constraints. Therefore, the connection is made through sharing nodes. Meanwhile, the two ends of t. The failure mode of the single-pipe solar greenhouse structure is the collapse of the greenhouse structure. In addition to the self-weight of the greenhouse structure, crop load and th.

Are single-tube skeletons safe for Chinese solar greenhouses?
In recent years, the use of single-tube skeletons for the construction of Chinese solar greenhouses has increased. As a consequence, during the selection of the construction materials, the safety of these structures has become an important issue.
What is the failure mode of single-pipe solar greenhouse structure in Shenyang?
The failure mode of the single-pipe solar greenhouse structure is the collapse of the greenhouse structure. In addition to the self-weight of the greenhouse structure, crop load and the concentrated load of the roof structure, the main external factor that causes the collapse of the greenhouse structure in Shenyang is the snow load.
What size tie rod for Chinese solar greenhouse skeleton?
In the present research, the optimum size of the single tube for the Chinese solar greenhouse skeleton to be used in the Shenyang region was calculated (Table 3 ). According to our results, the tie rod should be made of a 30 × 2 mm round tube, while the tie bar reinforcement of a 20 × 2 mm round tube.
What are Chinese solar greenhouses?
Chinese solar greenhouses are agricultural facilities that have been used in north China for crop cultivation without additional heating during severe cold weather 1. By the end of 2017, the total area of horticultural facilities in China had reached 3.7 million hm 2 2.
