Carmo, R.N.F.; Valença, J.; Silva, D.; Dias-da-Costa, D.Published 2015-01-01The measurement of steel strains in reinforced concrete structures is often critical to characterise stresses and forces along the member. In this scope, this manuscript describes the development of a method to assess steel ...Open AccessArticle
Dias-da-Costa, D.; Valença, J.; Julio, E.; Araujo, H.Published 2017-01-01An image deformation method is herein proposed to monitor the crack propagation in structures. The proposed approach is based on a computational algorithm that uses displacements measured by photogrammetry or image correlation ...Open AccessArticle
Simões, T.; Octávio, C.; Valença, J.; Costa, H.; Dias-da-Costa, D.; Júlio, E.Published 2017-01-01The 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 fibre/matrix interface. With this aim, ...Open AccessArticle
