4 Check for Blower Foundation Design

4.1 The Mass Ratio

(1) Foundation weightW c = [(FL*FB*FH)+(PL*PB*PH)] * Unit wt of Concrete

(3) Mass Ratio SAES Q-007R = Wc / Wm > 3 = cl 6.1.2

Condition: Ratio > 5, for reciprocating equipment

4 Check for Blower Foundation Design

4.1 The Mass Ratio

(1) Foundation weightW c = [(FL*FB*FH)+(PL*PB*PH)] * Unit wt of Concrete

= 24 *((2*5*0.9)+(0*0*0)) = kN

(2) Machine weight

= kN

(3) Mass Ratio SAES Q-007R = Wc / Wm > 3 = cl 6.1.2

Condition: Ratio > 5, for reciprocating equipment

Condition: Ratio > 3 , for rotating equipment

3.28

Hence OK

216.00

Wm = Weight of blower + Weight of motor + Weight of base plate + Weight of Silencer 65.87

4.2 The Minimum Thickness of Concrete Foundation

SAES Q-007

FH + PH ≥ 0.6 + FB / 30 (m) cl 6.1.3

4.3 The Width of Concrete Foundation

SAES Q-007

FL > 1.5 * Vertical Distance From the Base to the Machine Centerline cl 6.1.4

2 > 1.350

4.4 Allowable Soil Bearing Pressure (Static)

= (216+65.87415)/(2*5) = kN/m2

(Low Tuned Foundations) = kN/m2SAES Q-007

cl 8.2

4.5 Allowable Eccentricities for Concrete Foundation

W1 = Wc + Wm = kN

X' = = m

SAES Q-007

Eccentricity in X-Direction cl 7.1

= (100*((5/2)-2.5))/2 = Condition : 5%

Hence OK

0.90 0.767 Hence OK

Hence OK
