SEISMIC CALCULATION FOR SPECTRUM FILTER 233-062

Notation:Z = Seismic zone factorI = Importance factorC=Dynamic response spectrum valueRw = Structural system coeffcientW = System operating weightV = Base shearh= Center of Gravity (Vertical Z direction)

Design Varibles:Z=0.4 for Seismic zone 4I=1.25Rw=4W=3300 lbsC=2.75h=57Supporting Leg Size = 3"x3"x1/4" anglesHold Down Bolt Size = 7/8"

Base shear:V = (Z*I*C/Rw)*W =(0.4*1.25*2.75/4)*3300 = 1134.38 lb

Overturn moment:M = V*h = 1134.38*57 = 64659.66 in.lb

Bending moment in supporting legsM1=((V/4)*L)/2 = ((1134.38/4)*60)/2 = 8507.85 in.lb

Moment of initia Ix and Iy (leg cross section)Ix=Iy=(t*a^3*(4*a+b))/12*(a+b) =(0.25*3^3*(4*3+3))/12*(3+3) =1.41 in^4

Bending stress in legs

= 8507.85*2.1/1.41s = M*c/Ix

Maximum uplift load on hold down boltsQ=(W/N) -(4*M/N*B) = (3300/4)-(4*64659.66/4*27) = 825 - 2394.80

Maximum bolt stress

= 1569.80/0.419

= 12671.27 psi < 17000 psi OK!

= -1569.80 lb Uplift!

s1 = Q/A

= 3746.53 psi < 25,000 psi OK!

SEISMIC CALCULATION FOR APU 100-006

Notation:Z = Seismic zone factorI = Importance factorC=Dynamic response spectrum valueRw = Structural system coeffcientW = System operating weightV = Base shearh= Center of Gravity (Vertical Z direction)

Design Varibles:Z=0.4 for Seismic zone 4I=1.25Rw=4W=13885 lbsC=2.75h=34Supporting Leg Size = 2"x2"x1/4" anglesHold Down Bolt Size = 7/8"

Base shear:V = (Z*I*C/Rw)*W =(0.4*1.25*2.75/4)*13885 = 4772.97 lb

Overturn moment:M = V*h = 4772.97*34 = 162280.93 in.lb

Bending moment in supporting legsM1=((V/12)*L)/2 = ((4772.97/12)*8)/2 = 1590.98 in.lb

Moment of initia Ix and Iy (leg cross section)Ix=Iy=(t*a^3*(4*a+b))/12*(a+b) =(0.25*2^3*(4*2+2))/12*(2+2) =0.416 in^4

Bending stress in legs

= 1590.98*1.5/0.416

Maximum uplift load on hold down boltsQ=(W/N) -(4*M/N*B) = (13885/12)-(4*162280.93/12*54) = 1157 - 1101

Maximum bolt stress

= 4772.97/(0.419*12)

s = M1*c/Ix

= 5736.70 psi < 17000 psi OK!

= 56 lb No Uplift!

s1 = V/A

= 949.27 psi < 25,000 psi OK!
