AbstractEarly-age cracking of high-performance concrete results in premature reinforcement corrosion, concrete spalling, high maintenance cost and reduced service life but design codes do not completely address early-age behavior of concrete. This paper presents a sensitivity analysis in which a finite element model of a bridge barrier wall constructed over an existing slab is used with actual field data to assess the sensitivity of relevant concrete properties to the development of total stress in the concrete barrier wall at early age. The parameters considered in the analysis include tensile strength, modulus of elasticity, maturity, thermal effects, shrinkage and creep. It reports the imitations of existing models and research needs.
