Figure 9. Time histories of the means and standard deviations of the axial stress acting on Member #14294 and vertical deflection of Node #3019 in sub-region Z10. For ease of analysis, the roof is divided into 18 sub-regions (6 sub-regions $$ \times $$ 3 sub-regions) of the same size (36 m $$ \times $$ 30 m) that are sequentially labeled Z1 to Z18. (A) Mean of the axial stress acting on a member stress acting on a member; (B) standard deviation of the axial; (C) mean of the vertical deflection of a node; (D) Standard deviation of the vertical deflection of a node.
