【 摘 要 】

Finite Element Analysis (FEA) was conducted on these four Beam Enclosure Assembly drawings: (1) AAA97-108954 (Quad); (2) AAA97-108981 (Quad Intermediate); (3) AAA98-101193 (Bundle); and (4) AAA97-108982 (Double Quad). Each drawing chosen represents one of the four enclosure types: Quad, Quad Intermediate, Bundle, and Double Quad. They were chosen because they have the longest length between supports for their type and are therefore the worse case condition from the standpoint of seismic induced stress. The purpose of the analysis was to find the maximum acceleration that each enclosure assembly can withstand and with this value determine the safety factor.
