Answer:
The design of a square tied column to support the given loads would require a side length of approximately 0.075 inches.
Explanation:
To design a square tied column, we need to calculate the required dimensions and reinforcement for the given axial dead and live loads.
Step 1: Calculate the total axial load:
Total axial load = Dead load + Live load
Total axial load = 120 k + 215 k = 335 k
Step 2: Determine the required cross-sectional area:
Total axial load = Cross-sectional area × Allowable stress
335 k = Cross-sectional area × 60000 psi
Cross-sectional area = 335 k / 60000 psi = 0.00558 sq.in.
Step 3: Find the side length of the column:
Assuming a square column, we have side length^2 = Cross-sectional area
Side length^2 = 0.00558 sq.in.
Taking the square root of both sides:
Side length = √(0.00558 sq.in.) ≈ 0.075 in.
Step 4: Calculate the longitudinal steel reinforcement:
Longitudinal steel desired = 3% of the cross-sectional area
Longitudinal steel desired = 0.03 × 0.00558 sq.in. ≈ 0.000167 sq.in.
Step 5: Check if the longitudinal steel reinforcement is feasible:
The provided reinforcement value is very small, so it may not be practical. Typically, minimum reinforcement requirements are set to ensure adequate strength and ductility.
In conclusion, the design of a square tied column to support the given loads would require a side length of approximately 0.075 inches.
