Question

A concrete slab is reinforced by $\frac{5}{8}-$ in. -diameter steel rods placed on 5.5 -in. centers as shown. The modulus of elasticity is $3 \times 10^{6}$ psi for the concrete and $29 \times 10^{6}$ psi for the steel. Using an allowable stress of 1400 psi for the concrete and 20 ksi for the steel, determine the largest bending moment in a portion of slab 1 ft wide.

Name: A concrete slab is reinforced by (5)/(8)- in. -diameter steel rods placed on 5.5 -in. centers as shown. The modulus of elasticity is 3 × 10^6 psi for the concrete and 29 × 10^6 psi for the steel. Using an allowable stress of 1400 psi for the concrete and 20 ksi for the steel, determine the largest bending moment in a portion of slab 1 ft wide.

Step 1

The diameter of the steel rods is $\frac{5}{8}$ in., so the radius is $\frac{5}{16}$ in. The cross-sectional area of a rod (A_rod) can be calculated using the formula for the area of a circle (πr²), which gives us: A_rod = π * ($\frac{5}{16}$ in.)² = 0.077 Show more…
