Allowable Bearing Pressure on Rock given Allowable Design Load Solution

STEP 0: Pre-Calculation Summary

Formula Used

Allowable Bearing Pressure on Rock = (Allowable Design Load on Rock Socket-(pi*Socket Diameter*Socket Length*Allowable Concrete-rock Bond Stress))/((pi*(Socket Diameter^2))/4)
q_a = (Q_d-(pi*d_s*L_s*f_g))/((pi*(d_s^2))/4)
This formula uses 1 Constants, 5 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Allowable Bearing Pressure on Rock - (Measured in Pascal) - Allowable Bearing Pressure on Rock is the lower of the maximum load that the footing can support.
Allowable Design Load on Rock Socket - (Measured in Pascal) - Allowable Design Load on Rock Socket is the lower of the maximum load a rock socket can bear.
Socket Diameter - (Measured in Meter) - Socket Diameter is the diameter of the socket which is twice the radius of the socket.
Socket Length - (Measured in Meter) - Socket Length is the total length of the socket.
Allowable Concrete-rock Bond Stress - (Measured in Pascal) - Allowable Concrete-rock Bond Stress is the allowed stress of concrete and rock bond.

STEP 1: Convert Input(s) to Base Unit

Allowable Design Load on Rock Socket: 10 Megapascal --> 10000000 Pascal (Check conversion here)
Socket Diameter: 0.5 Meter --> 0.5 Meter No Conversion Required
Socket Length: 2 Meter --> 2 Meter No Conversion Required
Allowable Concrete-rock Bond Stress: 2 Megapascal --> 2000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

q_a = (Q_d-(pi*d_s*L_s*f_g))/((pi*(d_s^2))/4) --> (10000000-(pi*0.5*2*2000000))/((pi*(0.5^2))/4)

Evaluating ... ...

q_a = 18929581.7894065

STEP 3: Convert Result to Output's Unit

18929581.7894065 Pascal -->18.9295817894065 Megapascal (Check conversion here)

FINAL ANSWER

18.9295817894065 ≈ 18.92958 Megapascal <-- Allowable Bearing Pressure on Rock
