About the Causes of the Koror Bridge CollapseDOI: 10.4236/ojsst.2014.42013, PP. 119-126 Keywords: Koror Bridge, Collapse, Causes, Cantilevers, Continuous Girder, Prestressed Concrete, State of Stress, Deflection, Stiffness Reduction, Probabilistic Evaluation Abstract:
This paper has been prepared from basic works published, mainly, after
2008 when the collapse investigation was made available. The main contributions
of the paper are: a proper model for the deflections at mid-span of the bridge,
the state of stress in elastic and post elastic stage for same phases of
behavior, the stage of cracked of the top of cantilever beams, the repair
effect on the structure of Koror Bridge, the probabilistic evaluation. The
present study is based on well known and simple engineer tools: the one-dimensional
beam-type was analyzed.
