Under its self weight (Distributed load due to self weight is w₁ = 4.5 kN/m) and a service point load P = 500 KN applied at 5 m away from the support (applied at the mid-span), check if the long term deflection at the mid-span at 5 years is within allowable limits according to TS3233 (the deflection limit is In/360). Take concrete compressive strength at transfer as fejk = 35 MPa, 28-day concrete compressive strength as fck = 40 MPa. The tendon eccentricity is 200 mm. The effective stress in prestressing steel fpe= 1000 MPa and prestressing steel area Aps = 1000 mm². Note: Obtain the deflection at the midspan due to a point load applied at the mid-span from your strength of materials knowledge. (You don't have to derive the formula, you can directly use it).
