Taken as 4.5 for Fire Sprinkler <br />Applications <br />I, Component Importance Factor. Taken as 1.5 for Fire Sprinkler Applications <br />W, Component Operating Weight. Taken as the weight of the Fire Sprinkler System in <br />the Z01 plus 15% <br />Z Height in the structure where the component attaches to the structure. Height is <br />relative to the base of the structure and shall not be taken as less than 0 and shall <br />not be larger than "H". <br />H Average roof height of the structure relative to the base <br />EQUATIONS <br />FPw = CPWP <br />Where: CP = 0.7 s 0.4SDs7v 1 + 2 <br />RH <br />P NJ <br />Where: SDs = 2/3 FaSs <br />CP,,,c = 0.7. 1.6SDi <br />CP min = 0.7 r 0.3SDslP <br />5 <br />
