Abstract

The service life of the bridges is affected by different factors that induce pathologies with possible consequences of collapse. Such factors influence the functionality, safety and stability. Therefore, engineering and research seek innovative solutions to address these problems in the long term. One of the main problems presented by the bridges in Chile is that scour produced in the area of the piers. there are several conventional methods of strengthening with the aim of improving their performance against erosion and scour processes. During 2012 a new method of strengthening has been investigated: Tied-arch method, proposing the modification of the static schema through the construction of an network arch. Based on this method, this paper provides the study and detailed proposal of constructive specifications of the main joints of its elements, including technical details (Drawing).
