Question

Column AB is made from high strength pre-cast concrete and reinforced with four 20 mm diameter A-36 steel rods. The allowable normal stress for the high strength concrete and the steel are $(\sigma_{allow})_{con} = 13$ MPa and $(\sigma_{allow})_{st} = 170$ MPa, respectively. The modulus of elasticity for high strength concrete is 29 GPa and for A-36 steel is 200 GPa. (Figure 1) Part A Determine the magnitude of the maximum allowable floor loading P. Express your answer to three significant figures and include the appropriate units. $P_{max} =$ Value Units Figure

Step 1

The side length of the square column is 225 mm. Area of concrete, $A_c = (225 \text{ mm})^2 - 4 \times \pi \times (10 \text{ mm})^2 = (225)^2 - 4 \pi (10)^2 = 50625 - 400\pi \approx 49370.6 \text{ mm}^2$ Area of steel, $A_s = 4 \times \pi \times (10 \text{ mm})^2 Show more…
