Fatigue strengthening of riveted girders in a historic railway metallic bridge in Switzerland using pre-stressed un-bonded CFRP laminates
In this paper, the applicability of the constant life diagram (CLD) methodology for fatigue strengthening of metallic members is described. The CLD methodology is a method that uses the combined effect of alternating stress, mean stress and material properties to predict the material life-time under high-cycle fatigue loading. The method could be used most efficiently to improve resistance to c...
متن کاملDesign criterion for fatigue strengthening of riveted beams in a 120-year-old railway metallic bridge using pre-stressed CFRP plates
This study presents a design criterion developed for fatigue strengthening of a 120-year-old metallic railway bridge in Switzerland and presents a pre-stressed un-bonded reinforcement (PUR) system developed to apply the strengthening. The PUR system uses carbon fiber reinforced polymer (CFRP) plates; however, unlike conventional pre-stressed CFRP reinforcement methods, preparation of the existi...
متن کاملFinite Element Analysis of Reinforced RC Bracket Using CFRP Plates
CFRP composites have unique application qualities such as high resistance and durability to environmental conditions, having relatively low weight and easy to install in strengthening concrete structure elements. The brackets should be strengthen sufficiently if they are not calculated and implemented well. Application of the CFRP is one of the methods for such purposes. The study involves usin...

متن کاملGlobal-local finite element analysis of riveted railway bridge connections for fatigue evaluation
Recent studies have found that stringer-to-cross-girder connections in riveted railway bridges are susceptible to fatigue cracking. Fatigue damage in these connections is caused by secondary, deformation induced effects. These effects are difficult to interpret in terms of a single, applied stress descriptor, which is customarily used in an S-N assessment. In order to address this problem, and,...
