Computer · Prestressed Concrete
A pre-stressed concrete beam 100 mm wide and 300 mm deep is pre-stressed by straight wires carrying an initial force of 150 kN at an eccentricity of 50 mm. Determine the loss of pre-stress due to elastic deformation of concrete if the area of steel wires is 188 mm2. Take ES = 210 kN/mm2 and EC = 35 kN/mm2.
