Assessment of the load-carrying capacity of existing structures with corroded smooth reinforcement bars
Paper i proceeding, 2017
Reinforced concrete bridges are common in Sweden and often damaged by reinforcement
corrosion that reduces the safety of the structure. This issue has been addressed in several research
projects with, however, a strong focus on ribbed bars, while further knowledge about smooth bars
is still needed. Edge beams from a bridge in Gullspång with naturally corroded smooth bars will
be studied so as to provide benchmark data for the assessment of the load-carrying capacity of
existing structures with corroded smooth bars. Structural tests are carried out on several beams,
with varying amounts of corrosion damage, measuring anchorage properties such as applied load
and end-slip.
