Transcribed Image Text:2. A simply supported rectangular concrete beam of span 8m has to be prestressed with a force
of 1600 kN. The tendon is of parabolic profile having zero eccentricity at the supports. The beam
has to carry an external uniformly distributed load of intensity 30 kN/m. Neglecting the self-
weight of the beam, the maximum dip (in meters, up to two decimal places) of the tendon at the
mid-span to balance the external load should be?
Span of the beam, L = 8m
Prestressing force, P = 1600 kN
%3D
U.D.L. on the beam, w = 30 kN/m
Maximum dip of tendon to balance the external load e = ?
