Surface roughness plays an important role in the behavior of concrete-to-concrete
interfaces. Methods like sand-blasting and hydrodemolition are usually adopted to improve …

The evolution of the crack pattern during laboratorial tests is quite important to adequately
characterise the specimen's response. Usually this is done by hand drawings. Hence, the …

The assessment of cracks in civil infrastructures commonly relies on visual inspections
carried out at night, resulting in limited inspection time and an increased risk of crack …

This manuscript presents an integrated approach for automatic crack monitoring combining
photogrammetry and image processing. In summary, the strain field obtained from …

The main objective of the research described in this paper was to evaluate how the concrete
compressive strength and the geometry of the steel fibres influence the behaviour of the …

Triaxial tests are used extensively to evaluate stress-strain behavior for both saturated and
unsaturated soils. A literature review indicates that all conventional triaxial test methods …

As reinforcing structural systems in RC (reinforced concrete) elements are continually
researched, more complex challenges in engineering are found that demand mathematical …

This paper aims at studying the shear contribution of steel fibres in concrete. Ten reinforced
concrete (RC) and steel-fibre reinforced concrete (SFRC) initially uncracked push-off …

An image deformation method is herein proposed to monitor the crack propagation in
structures. The proposed approach is based on a computational algorithm that uses …

Conventional deformation measurement techniques, such as utilizing a LVDT, a
demountable mechanical strain gauge (demec gauge), and an electrical strain gauge …
