ABSTRACT
Four beams were used in the test programme. Beam 1 was tested under self-weight; Beam 2 was tested under a constant sustained load that was equivalent to 10% of the ultimate load capacity of the beam (uncracked condition); and beams 3 and 4 were tested under a constant sustained load that was equivalent to 33% of the ultimate load capacity of the beam (cracked condition). Beams 1 to 3 were corroded under their respective loading systems whilst beam 4 was not corroded. A summary of the test programme is shown in Table 1.
