Question:medium
A simply supported prestressed concrete beam of span 30 m. The initial stress is 1000 MPa. The slip in the jack during tensioning has been 3 mm. If $E_s = 200$ GPa, the loss of prestress due to anchorage is:

Show Hint
Anchorage slip loss is a fixed magnitude of shortening. Therefore, the percentage loss is much higher for shorter beams than for longer beams. For very long spans, this loss often becomes negligible.
