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.
