A post-tensioned concrete beam, 170 mm wide and 320 mm deep,
is prestressed five wires of 8 mm diameter located at constant
eccentricity of 50 mm and carrying an initial stress of 840 N/mm.
The span of the beam is 10 m. Calculate the percentage loss of
stress in wires for The beam is pretensioned and The beam is post-
tensioned. Using the following data: Es = 210 kN/mm2, Ec = 35
kN/mm, Creep coefficient = 1.6, %3D Relaxation of...
