At high flexural damage, 38.3% reduction in shear strengthening efficiency was noted at higher ductility, while the flexural strengthening efficiency reduced by 65.7% at high shear damage, both from capacity perspectives.
Test results showed 57 76 % loss of strengthening efficiency and 43 48 % loss of stiffness due to exposure.
To evaluate the effect of preloading on the strengthening efficiency, the beam (B3) was strengthened without preloading.
However, it is not clear whether the fatigue behaviour and the CFRP strengthening efficiency is the same when the cracked-steel elements exhibit a state of complex loading.
The strengthened efficiency is mainly attributed to the improved catalytic activity of the modified PEDOT PSS films induced by the coarser surface and the lower sheet resistance.
The obtained experimental results of the RC beams strengthened with CFRP profiles are presented and discussed with the aim of evaluating the influence of CFRP profile reinforcement ratio on the strengthening efficiency of this technique.
The influence of the inclination and shear strengthening ratio of ETS on the shear strengthening efficiency was evaluated, as well as the interaction of ETS bars with existing steel stirrups.
The influence on the shear strengthening efficiency of the inclination and shear strengthening ratio of ETS configurations was evaluated; the study also examined the interaction of ETS bars and existing steel stirrups.
This paper provides details of an investigation into strengthening efficiency of FRP rehabilitated bridge deck slabs through tests conducted on slab sections cut from a bridge just prior to demolition.
The design variables investigated to evaluate the strengthening efficiency include the steel yield strength, the modulus of elasticity of the hoop fibre, and the amount and configuration of the fibre reinforcement.
