Florida Building Code - Existing 2007 http://www.villageofglenview.com Section E (The Calculations) For Moment based life systems, choose either Method 1 or 2. Compare the values for M_r. If the values are greater than or equal to the M_r values in the table, then the alternative method is acceptable. Method 1 (Moment Based) The Calculations Per RAS 127 D_r = D + L_r + 0.2S P_r = D + L_r + 0.2S M_r = D + L_r + 0.2S N_r = D + L_r + 0.2S NOA M_r = 66.5 NOA P_r = 66.5 NOA M_r = 66.5 NOA N_r = 66.5 Method 2 (Simplified TWC Calculation Per Table 127) Required Moment of Resistance (M_r) from Table 127 M_r Required Moment Resistance Roof Slope 0V 2V 3V 4V 6V 2/12 32.5 36.5 38.7 42.2 3/12 32.5 36.5 38.7 42.2 4/12 32.5 36.5 38.7 42.2 5/12 32.5 36.5 38.7 42.2 6/12 32.5 36.5 38.7 42.2 7/12 32.5 36.5 38.7 42.2 8/12 32.5 36.5 38.7 42.2 Must be used in conjunction with Table 127. For Lifts based life systems use Method 3. Compare the values for P_r with the values for P_r. If the P_r values are greater than or equal to the P_r values for each area of the roof, then the alternative method is acceptable. Method 3 (Lift Based The Calculations Per RAS 127) D_r = D + L_r + 0.2S P_r = D + L_r + 0.2S M_r = D + L_r + 0.2S N_r = D + L_r + 0.2S NOA P_r = NOA P_r = Where to Obtain Information Description Symbol Where to Obtain Information Snow Load S RAS 127/DOC 127 or weather.gov Ground Snow Load P_g RAS 127/DOC 127 or weather.gov Roof Slope S RAS 127/DOC 127 or weather.gov Exposure E RAS 127/DOC 127 or weather.gov Thermal Factor T RAS 127/DOC 127 or weather.gov Wind Speed V RAS 127/DOC 127 or weather.gov Importance Category I RAS 127/DOC 127 or weather.gov Roof Zone RZ RAS 127/DOC 127 or weather.gov Topographic Factor K_zt RAS 127/DOC 127 or weather.gov Seismic Design Category SDC RAS 127/DOC 127 or weather.gov Occupancy Category OC RAS 127/DOC 127 or weather.gov Basic Wind Speed V RAS 127/DOC 127 or weather.gov Exposure Category EC RAS 127/DOC 127 or weather.gov Risk Category RC RAS 127/DOC 127 or weather.gov 2 9
