Abstract：
Bamboo shading screens woven by thick horizontal bamboo strips and thin vertical bamboo strips can effectively block the direct solar radiation so that the cooling energy consumption can be reduced. At the same time, it enables adequate diffuse daylight penetration into the room, so as to maintain a bright and stable indoor daylight environment. Thus, it is considered to be an energy-efficient and sustainable solar shading screen. In this paper, the finite element models of such bamboo shadings in four different sizes were established, and the mechanical properties of the shading structures were simulated under different wind speeds and wind directions. The results show that, three structures in sizes of 1 m×1 m, 1.5 m×1.5 m, 3 m×1 m meet the stiffness requirements, while structure in a size of 3m×3m fails to meet the rigidity requirement due to the deformation excessive. A combined structure by 1m×1m or 1.5m×1.5m or 3m×1m is suggested for a large size of shading screen. Because bamboo has good mechanical properties, each size of the structure can meet the strength requirement. Results of this study can be used as a reference for the design and application of such woven bamboo solar shading screens.
