continuous beam ABC (AB = BC = 10 m) has a rectangular section, 400 mm wide and 650 mm deep. The beam is prestressed by a concordant cable having a cross-sectional area of 1200 mm², located 50 mm from the soffit at mid-span points and 50 mm from the top of beam at B. If the beam supports two concentrated loads of 200 kN each at mid-span points, determine the load factor against collapse assuming, (a) elastic distribution of moments, and (b) complete redistribution of moments.
