Modifi cation of bending moment due to creep
distribution of the self weight bending moments, is minimised. The use of prestressing,
as described below, helps in that respect.
If the beam had been made of prestressed concrete rather than reinforced concrete,
the principles would be identical, but the results would be quite different. For instance,
if the statically determinate beam had been prestressed with a parabolic cable that
