Study on strength of glass greenhouse (part 2)

Actual size experiments on roof and wall

Abstract

About the glass greenhouse which became a big area, we did the actual size experiment on roof and wall that assumed the displasement of situation in earthquake wave transmitted to longitudinal direction. As for experiments result, the deformation in that case where the damage appeared to glass was more than the deformation of earthquake response analysis results and there was no problem with current glass miter joint method.
And we did the experiment that reproduced the snow load and negative pressure by high wind to work on roof side. By this experiment result, we grasped being different in strength by the load worked direction and the cause that strength was decided. And we examined correspondence with provided strength and load of each place determined by greenhouse structure standard.
