| Abstract: |
Inspection of structures is usually a straight forward and routine activity mainly concerned with serviceability issues but on occasions it can present problems. These problems arise when critical defects are hidden from view and if left to develop can lead to collapse of the structure without warning. In practice there have been a number of occasions when bridges have collapsed soon after an inspection which had shown that there were apparently no serious defects. Three very different examples having hidden defects are described and discussed. These involve a cast iron beam, a post-tensioned concrete deck and holding down bolts on a steel viaduct. |
