This paper presents the results of an investigation into the use of adhesively bonded carbon-fibre-reinforced polymer composites in reinforcing existing wrought iron structures. There has been concern that the laminar structure of the wrought iron would result in premature failure of the bonded reinforcement. The lap-shear and inter-laminar shear tests reported here show that adhesive strength, as in strengthening of steel or cast iron structures, will be the deciding factor in the reinforcement design. It is concluded that composite strengthening of wrought iron is technically satisfactory subject to certain precautions and methods for practical implementation are discussed.

“…Due to the presence of large slag inclusions parallel to rolling direction that were generated during fabrication of puddle iron plates, yield stress fy is typically lower in the transversal direction [42,43]. Based on a previous study by the authors [9], a significant amount of longitudinal non-metallic inclusions was observed on micrographs of puddle iron plates from Redondela bridge.…”

A local and global finite element analysis of the stringer-floor beam connection of a 19th century riveted railway bridge in Spain made of puddle iron were performed to obtain the maximum principal strains in the riveted connecting angles corresponding to bending moments from train loading on the bridge. Due to the anisotropic nature of puddle iron, the connecting angles were modelled using Hill anisotropic plasticity potential and a parametric study in the local FE model of the connection was performed. A laboratory specimen fabricated with original stringers dismantled from the railway bridge was tested to calibrate the numerical models, so the yield stress ratio that best fitted experimental results was obtained. Based on the method of constant fatigue-life diagram and modified Goodman fatigue failure criterion, it was detected that the connecting angles were prone to fatigue crack initiation, as the combination of mean stress and alternating stress amplitude at the toe of the angle fillet remained outside the infinite fatigue-life region. An innovative strengthening system based on adhesively-bonded carbon-fiber reinforced polymer (CFRP) angles was designed to prevent fatigue crack initiation in the connecting angles of the stringer-floor beam connection. Different CFRP laminate layouts were numerically evaluated and a proper configuration was obtained that reduced both the mean stress and the alternating stress amplitude in the connecting angle to shift from finite fatigue-life region to infinite fatigue-life region in the constant fatigue-life diagram. To validate the effectiveness of the proposed CFRP strengthening method, its application on a second laboratory specimen fabricated with original stringers was evaluated experimentally and compared with numerical results. The research study conducted showed that the use of adhesively-bonded CFRP angles was an effective strengthening system in reducing the stress level in the fillet region of the puddle iron connecting angles (where fatigue cracks are prone to initiate) and consequently could increase fatigue life of the stringer-floor beam connection.
