GATE Civil Engineering (CE) 2017 Shift 1 Solved Paper

A pre-tensional rectangular beam 150mm wide and 300 mm depth is prestressed with three straight tendons each having a cross-sectional area of 50 mm² to an initial stress of 1200 N/mm². The tendons are located at 100 mm from the soffit of the beam if the modular ratio is 6 the loss of prestressing force (in kN up to one decimal place) due to the elastic deformation of concrete is ________
