Question

CALCULATE THE MAXIMUM STRESS AT CORNOR IF 4600KG WHEEL LOAD IS APPLIED ON CEMENT CONCRETE PAVMENT OF THICKNESS 180MM

Answer 1

Step-by-step explanation:

Wheel load, P = 5100 kg

Modulus of elasticity of cement concrete, E = 3.0 x 105kg/cm2

Pavement thickness, h = 18 cm

Poisson's ratio of concrete, μ = 0.15

Modulus of subgrade reaction, K = 6.0 kg/cm3

Radius of contact area, a = 15 cm

Answer 2

The maximum stress at corner is $42.59\ kg/cm^2$

Step-by-step explanation:

• Mass of the wheel, m = 4600 kg

• Thickness of the pavement, h = 180 mm = 18 cm

• We need maximum stress at corner. To find the the stress the formula is as follows :

$\sigma=\dfrac{3m}{h^2}\\\\\sigma=\dfrac{3\times 4600}{(18)^2}\\\\\sigma=42.59\ kg/cm^2$

• So, the maximum stress at corner is $42.59\ kg/cm^2$.
