To calculate the percentage loss of pre-stress due to anchorage slip, we can use the formula:

Percentage Loss = (Slip / Length) * 100

where Slip is the amount of slip in mm and Length is the length of the beam in mm.

In this case, the slip is given as 3 mm and the length is given as 30 m (which is equal to 30000 mm).

Percentage Loss = (3 mm / 30000 mm) * 100
= 0.01 * 100
= 1%

Therefore, the percentage loss of pre-stress due to anchorage slip is 1%.

Calculation:
Given,
Anchorage slip = 3 mm; Beam length = 30 m; Modulus of Elasticity of steel = 2.1 × 105 N/mm2, initial pre-stress = 1200 N/mm2

∴ Loss in pre-stress = 1.75%
