The trusses are located on <br /> 18'-0" centers and span 64'-0". Located at each panel point oi the truss <br /> bottom chords are 6x10 beams wliirh span 18'-0" between the trusses. <br /> The existing ceiling joists are hung irom these beams. <br /> At the present time a new ceiling is being erected. The new ceiling <br /> joist are supported on walis running perpendicular to the trusses located <br /> Ib'-0° from each end,and are hung from the 6x10 beam at the truss mid- <br /> span. <br /> Aiter completing a thorough stress analysis ot the roof, it is our opinion <br /> ihat the existing trusses and beams are sufficient to support the expected <br /> roof live loads, the existing ceiling and roof dead loads, and the loads <br /> imposed by thc new cciling. <br /> ' ' Respectiully submitted, <br /> STR TURA `DE�IGN ASSOCIATLS, INC. <br /> by; � `S�,VANpF� <br /> � � � � .a�� F.SIGk „ F'L <br /> � I / 1 1 ,� /� 0 ��0 r O <br /> ;' /�� \. ��,V / :/1. � 1 �/' Q<� Q ^�o1W�5q/,C C9A � <br /> Kase Vanden Cndc, P.E.
