ABSTRACT This study investigates the feasibility of an alternative structural health monitoring (SHM) technique for an existing, post-tensioned, prestressed concrete bridge in Niigata, Japan. Currently, a static SHM system is in place to detect the progress of damages within the bridge. However, the existing system cannot properly monitor the structural health of the bridge including the periodic vibration, which is one of the damage-sensitive features of interest. Therefore, to effectively detect the real-time performances of the bridge, a three-dimensional (3D) Finite Element (FE) model was developed as a reference and verified using on-site load-deflection test results. After validating the reference FE model, different damage scenarios, such as degradation of concrete, corrosion & rupture of steel tendons and missing tendons, were incorporated in the FE models. Based on non-linear structural and Eigenvalue analyses, natural frequencies and mode shapes of the bridge remain constant even after careful consideration of all types of damages in the FE model. However, vertical displacements are observed to increase for the damage scenarios. Although the effect of tendon rupture and corrosion showed negligible influences on the vertical displacement, the deterioration of the concrete largely influenced the vertical displacement. Additionally, crack widths were found to vary with damage types. Brifely, this study recommends some effective indicators to monitor the structural conditions of the bridge using FE analysis (FEA).

ABSTRACT Lignin is a natural polymer that has antioxidant properties. However, a supplied lignin’s physical, chemical, and rheological behaviour will differ from the source. Thus, the objective of this work was to investigate the mechanical performance of asphalt mixtures produced with asphalt binders modified by lignins at the contents of 0, 3, 6, and 9%, from pinus and eucalyptus sawdust. The mixtures were evaluated by performing the Splitting Tensile Strength Test, Lottman, Resilient Modulus, and Dynamic Modulus. The results pointed to lignin, both tested, as a good natural polymer due to the increase in resilience of the asphalt mixtures and reduction of susceptibility to moisture for the proposed contents. Therefore, it is suitable for field use. Lignin can be identified as a residual modifier that can provide longer service life to asphalt coatings, presenting itself as an alternative modifier to the synthetic elastomeric polymers. The addition of 3% pinus lignin presented the best mechanical performance, followed by the addition of 9% eucalyptus lignin.

ABSTRACT This study investigates the performance of recycled aggregate concrete incorporating different sizes and concentrations of coarse aggregate under sodium sulphate and normal water curing. Ten mixes were produced, having two control mixes of 12 to 20 mm and 5 to 12 mm coarse aggregate size. The rest of the mixes have supplementary cementitious material with 0%, 15%, 30%, and 45% substitution of respective sizes normal aggregate by recycled aggregate. The fresh recycled aggregate concrete mixes were assessed through the slump, ball penetration, and compacting factor test, which exhibited a falling trend with the percentage increase of recycled aggregate. Moreover, compressive strength and ultrasonic pulse velocity drop with the percentage of RCA increases at 7, 28, and 91-days normal curing and 5% Na2SO4 solution curing at 91 days. The compressive strength and ultrasonic pulse velocity of 5-12 mm coarse aggregate concrete showed improvement over 12–20 mm coarse aggregate concrete of the same replacement for both curing. However, 5% Na2SO4 solution curing specimens exhibit around 5–11% decrease in compressive strength and higher penetration depth than normal curing . Furthermore, the outer face of the silica fume included samples have received fewer white patches after sodium sulphate immersion.
