Experimental wind load model for heliostats

Zang, Chuncheng; Wang, Zhifeng; Liu, Hong; Ruan, Yi - In: Applied Energy 93 (2012) C, pp. 444-448

experiments on an actual heliostat rather than a wind tunnel heliostat model. The tested factors include the strain in the … use in a finite element analysis of the heliostat. The finite element results agree with the experimental data; therefore …

Wind tunnel test of snow loads on a stepped flat roof using different granular materials

Zhou, Xuanyi; Hu, Jinhai; Gu, Ming - In: Natural Hazards 74 (2014) 3, pp. 1629-1648

An accurate prediction of wind-induced redistribution of snow load on roof surfaces is vital to structural design. To represent the pattern of snow distribution caused by snowdrift in wind tunnel test, appropriate modeling particles should be selected. The particle density is the key to...
