Losses in prestressed concrete

Prestressed Concrete Losses Calculator as per IS 1343 (1980)

This calculator computes all major losses in prestressed concrete based on IS 1343:1980. For IRC standards, similar provisions apply for bridges (IRC 112 refers to IS 1343 for losses). Inputs are required for accurate calculation.

Type of Prestressing: Pre-tensioned Post-tensioned Characteristic Concrete Strength f_ck (MPa): Initial Prestress f_p0 (MPa): Concrete Stress at Tendon Level f_cgp (MPa): Modulus of Concrete E_ci (MPa): Modulus of Steel E_s (MPa): Age at Loading t_0 (days): Relative Humidity RH (%):

Friction Coefficient μ: Cumulative Angle α (radians): Wobble Coefficient k (1/m): Distance from Jacking End x (m): Anchorage Slip δ (mm): Tendon Length L (m):

Steel Type for Relaxation: Normal Relaxation Low Relaxation Initial Stress Ratio (f_pi / f_pk):
