... safely. Scouring at the contracted section of approaching flow is a significant cause of bridge abutment failure. The main objective of this study was to estimate the geometry of the equilibrium contraction scour at a protruding abutment bridge in the compound channel, using parametric analysis (PA...

... an understanding of the anatomy of the partial failure. Following the investigation, the mystery of the Izbor viaduct was revealed. Three types of load were predicted and incorporated in the analysis: self-weight of the viaduct, temperature gradient and cable-stay post-tensioning forces. Post-tensioning forces...

... are damaged thereby causing local failure, the through-arch bridge will not be endangered and will still maintain reasonable overall load-carrying capacity so that the necessary emergency measures can be taken. Each hanger of a through-arch bridge is anchored to the arch rib at one end and a transverse...

... imposed by marching troops, Montrose and Yarmouth failed when crowds rushed from one side to the other to watch events passing beneath. It was found that both the failures caused by troops were at the suspension anchorages. Those caused by asymmetric crowd loading were in the main chains at badly forge...

...S. M. Wong, PhD, DIC; C. J. Onof, PhD, DIC, FSS; R. E. Hobbs, PhD, DSc(Eng), FICE, FIStructE One of the key factors in evaluating the risk level of a structure such as a bridge should be an examination of the failure consequences, considering that the risk equals the probability of failure times...

... that the evidence to support it is weak. Lewis and Reynolds 2 have asserted that the failure of the bridge was not mainly due to wind effects but instead was due to dynamic loading and fatigue. This represents a major change of viewpoint in relation to the fundamental reason for the collapse and merits serious...

... aged from 1908 to the 1990s. It was found that only 45% of the repairs were reported as being wholly successful when last inspected. Perceived causes of failures are considered and ways of making more durable repairs are outlined. 10 03 2004 16 08 2004 Fig. 4. Lives of repairs...
