Three-Dimensional Finite Element Analysis to Evaluate Reflective Cracking Potential in Asphalt Concrete Overlays
The study revealed that the crack treatment interlayer, ISAC, greatly reduces the tensile stresses at the bottom of the overlay after both the cooling cycle and cooling cycle plus traffic loading. On the other hand, the modified asphalt (PG 64-28) greatly reduces the tensile stresses at the top of …

Numerical modelling of time-dependent cracking and deformation of reinforced concrete structures
For a structure to remain serviceable, crack widths must be small enough to be acceptable from an aesthetic point of view, small enough to avoid waterproofing problems and small enough to prevent the ingress of water that may lead to corrosion of the reinforcement. Crack control is therefore an …

Structural Behaviour of Self Consolidating Steel Fiber Reinforced Concrete Beams
… resistance of reinforced concrete beams, enhance crack control and can promote flexural ductility. Despite extensive research, there is a lack of accurate and reliable design guidelines for the use of SFRC in beams. This study presents a rational model which can accurately predict the shear …

Numerical Modelling of Steel Fibre Reinforced Concrete Subjected to Fatigue Loading
… tension and thus susceptible to the formation of cracks when under tensile stresses. Steel Fibre Reinforced Concrete (SFRC) improves post-cracking behaviour through enhanced tensile strength, toughness, and crack control, offering increased resistance to fatigue damage. Despite extensive …

Continuity development between precast beams using prestressed slabs, and its effect on flexure and shear
… supports, prestressed slabs will ensure a crack free more durable bridge deck, and will therefore reduce the maintenance costs. The effect that such a slab has on flexural and shear behaviour of the bridge deck has been studied both analytically and experimentally by considering composite …

Prediction of service load of concrete structures after cracking using ultrasonic technique
The objective of this study is to investigate the cracking behavior of fractured concrete structures and to introduce a new approach to assess their remaining service lives. A novel ultrasonic technique is utilized to detect crack propagation in notched beams of mortar, plain concrete and …

The Role of Reactive MgO as an Expansive Additive in the Shrinkage Reduction of Concrete
… and in particular, reduces the quantity of crack control reinforcement used. The mechanism is similar to conventional ettringite-based and lime-based expansive admixture relying on their expansion to offset concrete shrinkage. In other words, the tensile stresses induced by concrete …

Behavior of RC hollow circular columns reinforced with GFRP bars and spirals under concentric and eccentric loads
L’un des problèmes les plus graves auxquels sont confrontées les structures en béton armé d’acier est la détérioration des éléments structuraux causée par l’aggravation des problèmes de corrosion de l’acier, en particulier dans les environnements difficiles tels que les structures marines, les …
