Strengthening of Masonry Bridges
Abstract The mechanical characteristics of materials and the interaction between the different elements of masonry bridges, typically arched ones, determine their behaviour, performance, structural deficiencies and failure modes. Therefore, it is particularly important to identify relationships between the main structural issues of this bridges’ type and the structural defects most commonly found, in order to allow defining appropriately sustained repair and/or reinforcement intervention programs for existing masonry bridges. This chapter presents a brief systematization of the structural behaviour of masonry arch bridges, with more emphasis on stone made ones, their relation with frequent structural damages and the identification of suitable rehabilitation and strengthening solutions. The structural behaviour of both the bridges and their structural elements is first addressed, focusing on mechanisms of load transmission across the bridge system, deficiencies and possible failure modes which are characteristic of bridges in operating conditions. A brief overview on damage and degradation present in masonry arch bridges is given in this chapter, concerning possible interventions deemed sufficient to ensure or restore the regular operation of these constructions. The main interventions on arch bridges, herein addressed, aim at correcting material and structural deterioration effects, to prevent further deterioration or to restore the existing system without changing bridge genuineness and construction authenticity.
