Question: A continuous beam has spans A B = 1 0 m , B C = 1 0 m . D is point in span B

A continuous beam has spans AB=10m,BC
=10m.D is point in span BC such that BD=DC.
The prestressing force P=200kN. The
prestressing cable has straight profile in span
AB and parabolic profile in span BC. The
eccentricities with respect to neutral axis as
shown in figure are eA=40mm,eB=
20mm,eD=20mm. The cable has zero
eccentricity at C.
a) Determine the resultant bending moment
diagram.
b) Sketch the C-line with respect to the c.g.s
line indicating the offsets at sections
corresponding to A,B,C,D.
A continuous beam has spans A B = 1 0 m , B C = 1
