A continuous beam ABC (AB = BC = 15 m) has a rectangular section 300
mm wide and 500 mm deep, throughout the two spans and is prestressed by a concordant cable having a cross-sectional area of 1500 mm2 located at 45 mm from the top of the beam at B. If the beam supports a uniformly distributed superimposed service load of 3.95 kN/m throughout the spans, estimate the load factor against failure assuming. Adopt p = 1450 N/mm2 and fck = 45 N/mm2, c = 25 kN/m3, pu = 1050 N/mm2, xu = 292mm. Find:
a. Elastic distribution of moments
b. Complete redistribution of moments (2 pts.)
