' � August 10, 2011 <br /> i 90 Ft Self-Supporting Tower Structural Analysis A2G0082A Pasco County (VS) <br /> Project Number 110908, Revision 3 Page 5 <br /> 3.1) Analysis Method <br /> RISATower (version 5.4.2.0), a commerciaily available analysis software package, was used to create <br /> a three-dimensional model of the tower and calculate member stresses for various loading cases. <br /> Selected output from the analysis is included in Appendix A. <br /> 3.2) Assumptions <br /> 1) Tower and structures were built in accordance with the manufacturer's specifications. <br /> 2) The tower and structures have been maintained in accordance with the manufacturer's <br /> specification. <br /> 3) The configuration of antennas, transmission cables, mounts and other appurtenances are as <br /> specified in Table 1. <br /> 4) TEP assumed the following material properties: <br /> a) Legs ASTM A572 Gr. 50 <br /> b) Bracing: ASTM A36 <br /> c) Anchor Bolts. ASTM A354-BC <br /> 5) Serviceability with respect to antenna twist, tilt, roll, or lateral translation, is not checked and is <br /> left to the carrier or tower owner to ensure conformance See Table 6. <br /> 6) This report is not a construction document. <br /> 4) ANALYSIS RESULTS <br /> Table 4- Component Stresses vs. Capacity <br /> Section Component Critical SF*P allow °h <br /> � Elevation (ft) Ty � Size Element P �� b � (Ib) Capacity Pass / Faii <br /> T1 190 - 180 Leg PIPE 2.5 STD (SCH 40) 1 -8631 010 57361.699 15.0 Pass <br /> T2 180 - 160 Leg PIPE 3.5 STD 19 -45971.699 104062.000 44.2 Pass <br /> T3 160 - 140 Leg Pipe 5 STD (SCH40) 49 -94977 703 169395.000 56.1 Pass <br /> T4 140 - 120 Leg Pipe 5 STD (SCH40) 73 -153820.000 169395.000 90.8 Pass <br /> T5 120 - 100 Leg PIPE 8 STD (SCH40) 97 -213486.000 �358212.000 59.6 Pass <br /> T6 100 - 80 Leg Pipe 10 STD (SCH40) 121 -268821.000 498329.000 53.9 Pass <br /> T7 80 - 60 Leg Pipe 10 STD (SCH40) 139 -329047.000 498329.000 66.0 Pass <br /> T8 60 - 40 Leg Pipe 12 STD (SCH40) 157 -389082.000 623679.000 62.4 Pass <br /> T9 40 - 20 Leg Pipe 12 STD (SCH40) 175 -448150.000 :623679.000 71.9 Pass <br /> T10 20 - 0 Leg P12EH 193 -506664.000 _822322.000 61 6 Pass <br /> T1 190 - 180 Diagonal Li 3/4x1 3/4x3/16 11 -2877.530 6609.350 43.5 Pass <br /> T2 780 - 160 Diagonal L2x2x3/16 25 -6370.840 9594.310 66.4 Pass <br /> T3 160 - 140 Diagonal L2 1/2x2 1/2x3/16 55 -8647.630 11468.900 8 9 j"� Pass <br /> T4 140 - 120 Diagonal L3x3x3/16 84 -10878.800 15865.600 68.6 Pass <br /> T5 120 - 100 Diagonal L3x3x3/16 108 -11824.600 14123.400 83.7 Pass <br /> T6 100 - 80 Diagonal L3 1/2x3 1/2x1/4 131 -15127.900 20565.100 73.6 Pass <br /> T7 80 - 60 Diagonal L3 1/2x3 1/2x1/4 149 -15996.100 17943.100 89.1 Pass <br /> T8 60 - 40 Diagonal L3 1/2x3 1/2x3/S 167 -17291 100 23301 100 74.2 Pass <br /> T9 40 - 20 Diagonal L3 1/2x3 1/2x3/8 185 -18044.301 20601.000 87 6 Pass <br /> T10 20 - 0 Diagonal L4x4x3/8 203 -19403.699 26494.900 73.2 Pass <br /> T1 190-180 TopGirt L31/2x31/2x1/4 5 -1151.280 24069.100 �Z'� Pass <br /> T2 180 - 160 Top Girt L3 1/2x3 1/2x1/4 23 -412.031 24491 400 � �� Pass <br /> T3 160 - 140 Top Girt L3 1/2x3 1/2x3/8 54 -58.854 36987.898 0.2 Pass <br /> RISATower Report - version 5.4.2.0 <br />
