B. DESCRIPTION OF STRUCTURE <br />The roof top structure is constructed of a series of welded aluminum assembliesconnected by high strength bolted butt splices. The assembled roof top structureis composed primarily of a canvas covered roof top measuring approximately 65ft. x 45 ft. in plan supported on six (6) towers approximately 35 ft. in length. Inaddition there are two (2) 24 ft. x 24 ft. sound wings supported on four (4)outboard towers for the support of sound equipment. The roof top structure is tobe used in the vicinity of the state of Nevada. <br />After the roof top is assembled on the ground, it is designed to travel up the towerlegs to its final position approximately 30 ft. above the base of the structure. Anisometric view of the roof top in its final position is shown in Figure 1. Stability towind uplift and overturning forces will be offered by a series of wire guysanchored to the ground, and ballast applied to the six (6) roof towers and four (4)sound wing towers. In addition, the guys will provide lateral support at the top Ofthe towert which contributes to the structural capacity of the tower sections.The proposed guy arrangement is shown in Figures 2 and 3. <br />The roof top structure is constructed of 6061-T6 aluminum welded with ER4O43filler alloy. High strength bolts are 5/8" dia. SAE, Grade 8 (equivalent to ASTMA354, Gr. BD) bolts. The section0 properties and structural capacities of theassembled welded aluminum components to be used for the sound wings areSummarized in Appendix A. <br />q <br />V <br />1 <br />2
