This paper presents design procedures for fibre reinforced polymer (FRP) systems inserted in the cover of concrete elements according to the near-surface mounted (NSM) technique. Such strengthening system depends greatly on their bond strength. Two e... Read More about Designing NSM FRP systems in concrete using partial safety factors.

Seismic assessment of a heavy-timber frame structure with ring-doweled moment-resisting connections (2017)
Journal Article
Rodrigues, L. G., Branco, J. M., Neves, L. C., & Barbosa, A. R. (in press). Seismic assessment of a heavy-timber frame structure with ring-doweled moment-resisting connections. Bulletin of Earthquake Engineering, https://doi.org/10.1007/s10518-017-0247-y

The performance of heavy-timber structures in earthquakes depends strongly on the inelastic behavior of the mechanical connections. Nevertheless, the nonlinear behavior of timber structures is only considered in the design phase indirectly through th...

On the robustness to corrosion in the life cycle assessment of an existing reinforced concrete bridge (2017)
Journal Article
Cavaco, E. S., Neves, L. C., & Casas, J. R. (2017). On the robustness to corrosion in the life cycle assessment of an existing reinforced concrete bridge. Structure and Infrastructure Engineering, 14(2), 137-150. https://doi.org/10.1080/15732479.2017.1333128

Management of existing structures has traditionally been based on condition assessment, based on visual inspections, disregarding the susceptibility of different structural types to aging and deterioration. Robustness, as a measure of the effects of... Read More about On the robustness to corrosion in the life cycle assessment of an existing reinforced concrete bridge.

Using truck sensors for road pavement performance investigation (2017)
Conference Proceeding
Perrotta, F., Parry, T., & Neves, L. C. (2017). Using truck sensors for road pavement performance investigation.

Considering data from 260 articulated trucks, with ~12900 cc Euro 6 engines driving along a motorway in England (M18), the study first shows how different approaches lead to the conclusion that road pavement surface conditions influence fuel consumpt...

Bridge asset management using Petri-Nets (2017)
Conference Proceeding
Yianni, P., Neves, L. C., Rama, D., Andrews, J., & Dean, R. (2017). Bridge asset management using Petri-Nets.

Management of a diverse portfolio of assets is a demanding and complex task. Although extensive research has been carried out in bridge asset management models, the model developed in this study contains flexibility which is able to model a vast arra...

Route level analysis of road pavement surface condition and truck fleet fuel consumption (2017)
Conference Proceeding
Perrotta, F., Trupia, L., Parry, T., & Neves, L. C. (2017). Route level analysis of road pavement surface condition and truck fleet fuel consumption.

Experimental studies have estimated the impact of road surface conditions on vehicle fuel consumption to be up to 5% (Beuving et al., 2004). Similar results have been published by Zaabar and Chatti (2010). However, this was established testing a limi...

A big data approach to assess the influence of road pavement condition on truck fleet fuel consumption (2017)
Conference Proceeding
Perrotta, F., Parry, T., & Neves, L. C. (2017). A big data approach to assess the influence of road pavement condition on truck fleet fuel consumption.

In Europe, the road network is the most extensive and valuable infrastructure asset. In England, for example, its value has been estimated at around £344 billion and every year the government spends approximately £4 billion on highway maintenance (Ho...
