Explain the analysis of singly reinforced rectangular beams, Civil Engineering

Assignment Help:

Explain the Analysis of Singly Reinforced Rectangular Beams:

1. Determine the area of steel reinforcement, As. Multiply the number of bars by the area of each bar.

2. Calculate a = A_s.ƒ_y/ 0.85.ƒ'_c.b

3. Calculate the design moment capacity:

ΦMn = φ A_s.ƒ_y (d-a/2)

Where φ = 0.90 for flexure
