40	B.	SEISMIC LOAD (Fp)
41
42		According to UBC 97
43		Seismic Load = Fp = ap ca lp / Rp (1 + 3 hx / hr ) Wp
44
45		Since hx = hr
46		So	Fp = 4 ap ca lp Wp / Rp
47
48		Where	ap =	2.5		(Ref: Table 16-O)
49			ca =	0.3		(Ref: Table 16-Q)
50			lp =	1.5		(Ref: Table 16-K)
51			Rp =	3		(Ref: Table 16-O)
52			Wp =	400.3	kN
53
54		Thus
55			Fp =	600.5	kN
56
57		Height of CG of Equipment			H =	1.25	m
58
59		Overturning Moment =
60			Mot = Fp * H / 2 =		375.3	kN-m
