The following data of a pre-stress concrete are given: Beam dimension ; bxh = 300 mm x 600 mm Loads Super imposed dead load 7 KN/m Live load = 20 KN/m Unit Weight of concrete 23 KN/cubic meter The beam is simply supported on a span of 15 meters and are pre tensioned with total initialpre tensioned with total initial force of 1750 KN from low-relaxation strand with centroid 220 mm below neutral axis throughout the beam length .There is a 15% loss of stress at service loads. The concrete covering of the pre-stressed concrete is _____mm., the total dead load is _____ KN/m.
