Shear crack width assessment in concrete structures by 2D distributed optical fiber
(Elsevier, 2019-09)
Article
Restricted access - publisher's policyThis paper outlines the second part of an experimental study to show the capabilities of distributed optical fiber sensors (DOFS) in their application to the structural health monitoring (SHM) of the shear performance of ... -
Fatigue performance of distributed optical fiber sensors in reinforced concrete elements
(Elsevier, 2019-09)
Article
Restricted access - publisher's policyIn this paper, the authors present the results of a laboratory test where two reinforced concrete beams were instrumented with Distributed Optical Fiber Sensors (DOFS) to allow the monitoring g of strain in four different ... -
Fibre distribution and tensile response anisotropy in sprayed fibre reinforced concrete
(2018-02)
Article
Open AccessSprayed steel fibre reinforced concrete (SSFRC) is a material that tends to present anisotropy, due to the action of the spraying process inducing preferential fibre orientation. Despite numerous applications worldwide ... -
Expansions with different origins in a concrete dam with bridge over spillway
(Elsevier, 2018-02)
Article
Restricted access - publisher's policyConcrete dams with expansions from different origins are rare and scarcely documented in the literature, therefore their study gains special interest. This study presents the case of a 62-year-old concrete dam with signs ... -
Sustainability of column-supported RC slabs: fiber reinforcement as an alternative
(2019-07)
Article
Open AccessFiber-reinforced concrete has been used in structures without any additional reinforcement when the design is determined by transient load stages (precast segments for tunnels), in elements with favorable boundary conditions, ... -
Numerical assessment of external sulfate attack in concrete structures: a review
(2019-07)
Article
Restricted access - publisher's policyThe slow progress of the external sulfate attack and the large size and criticality of typical structures affected by this phenomenon establish numerical modeling as a key tool to assess the future evolution of concrete ... -
Characterization of pervious concrete exposed to high levels of evaporation
(2019-01)
Article
Restricted access - publisher's policyWhen fresh concrete is exposed to high levels of water by evaporation in structures with large ratios of surface/thickness these are prone to be altered in their constituent material properties, generating a decreased or ... -
Sustainable building technologies for post-disaster temporary housing: integrated sustainability assessment and life cycle assessment
(World Academy of Science, Engineering and Technology (WASET), 2019-04)
Article
Open AccessAfter natural disasters, displaced people (DP) require important numbers of housing units, which have to be erected quickly due to emergency pressures. These tight timeframes can cause the multiplication of the environmental ... -
Characterization of a fibre-reinforced self-compacting concrete with 100% of mixed recycled aggregates
(WIT Press, 2017-11)
Article
Open AccessA new cement-based material is presented in this research contribution. The material consists in a fibre-reinforced self-compacting concrete with 100% of mixed recycled aggregate. Six different mixes were produced in two ... -
Optimal metric for condition rating of existing buildings: is five the right number?
(Taylor & Francis, 2019-06)
Article
Restricted access - publisher's policyIn the context of the built environment in the recent years, the concept of maintenance has changed from corrective to preventive maintenance. There is evidence that preventive maintenance is much more efficient than ... -
Case study of failure of long prestressed precast concrete girder during lifting
(Elsevier, 2019-06)
Article
Restricted access - publisher's policyImprovements in concrete technology, reinforcing systems and manufacturing enable the use of longer reinforced precast concrete girders, contributing to the competitiveness of this solution for bridge decks. The weight of ... -
Distributed optical fibre sensors in concrete structures: performance of bonding adhesives and influence of spatial resolution
(Wiley, 2019-03)
Article
Restricted access - publisher's policyIn this paper, the authors conducted an experiment where a reinforced concrete beam was instrumented with a 5-m long polyimide single distributed optical fibre sensors (DOFS) performing four equal segments externally bonded ...
