To determine the limiting depth of the neutral axis in a singly reinforced beam, we need to consider the strain in concrete at the limit state of collapse. The formula used to calculate the limiting depth is given as:
x = (0.87 * h * σ_st) / (0.36 * f_ck)
Where:
x = limiting depth of the neutral axis
h = effective depth of the beam
σ_st = stress in steel
f_ck = characteristic compressive strength of concrete
Given data:
h = effective depth = 300 mm
f_ck = characteristic compressive strength of concrete = M20 grade = 20 N/mm²
σ_st = stress in steel = Fe 415 grade = 415 N/mm²
Substituting the values into the formula:
x = (0.87 * 300 * 415) / (0.36 * 20)
Calculating the value:
x = 220 mm
Therefore, the limiting depth of the neutral axis in the given singly reinforced beam is 220 mm.
- Formula: x = (0.87 * h * σ_st) / (0.36 * f_ck)
- Given data: h = 300 mm, f_ck = 20 N/mm², σ_st = 415 N/mm²
- Substituting the values: x = (0.87 * 300 * 415) / (0.36 * 20)
- Calculating the value: x = 220 mm
- Therefore, the limiting depth of the neutral axis is 220 mm.
x = (0.87 * h * σ_st) / (0.36 * f_ck)
Where:
x = limiting depth of the neutral axis
h = effective depth of the beam
σ_st = stress in steel
f_ck = characteristic compressive strength of concrete
Given data:
h = effective depth = 300 mm
f_ck = characteristic compressive strength of concrete = M20 grade = 20 N/mm²
σ_st = stress in steel = Fe 415 grade = 415 N/mm²
Substituting the values into the formula:
x = (0.87 * 300 * 415) / (0.36 * 20)
Calculating the value:
x = 220 mm
Therefore, the limiting depth of the neutral axis in the given singly reinforced beam is 220 mm.
- Formula: x = (0.87 * h * σ_st) / (0.36 * f_ck)
- Given data: h = 300 mm, f_ck = 20 N/mm², σ_st = 415 N/mm²
- Substituting the values: x = (0.87 * 300 * 415) / (0.36 * 20)
- Calculating the value: x = 220 mm
- Therefore, the limiting depth of the neutral axis is 220 mm.
