,Conservatek Industries, Inc. <br /> Dome Dead Load <br /> • The dead load is the weight of the structure and all material permanently attached to and supported <br /> by the structure. For the AlumadomeTM this includes the weight of the struts, hubs, fasteners, <br /> panels, strut caps, hub covers, and appurtenances. The total weight of all of these items for this <br /> dome is approximately: <br /> WT:= 15250•1bU, <br /> Expressing this load as a distributed load over the horizontal projected area of the dome: <br /> DL:= VAhVT DL=2.595 psf <br /> Calculate the vertical reaction (BDL)at each of the supports due to dome's dead load. <br /> WT <br /> BDL:= N <br /> • <br /> From geometry section: <br /> Ns=20 <br /> Solution: <br /> BDL=0.763 kips <br /> Radial Support Reaction for Dead Load (sliding supports) <br /> To calculate radial reaction due to friction in the Teflon sliding bearing, conservatively use 0.10 <br /> as the coefficient of friction between stainless steel and Teflon. <br /> RDL:= 0.10•BDL <br /> RDL=0.076 kips <br /> Prepared By: elf CT#: 206023 REV: 0 <br /> Date: 4/27/06 Page Number: 5 <br />
