An existing hydroelectric facility affected by alkali–aggregate reaction (AAR) is considered in
this study through numerical and experimental investigations. A new developed …

Shear keys provide interlocking mechanisms along the vertical contraction joints of many
concrete gravity dams. The shear key ultimate shear capacity is typically estimated as a …

This work focuses on the failure mechanisms of concrete hydroelectric facilities affected by
alkali–aggregate reaction (AAR). Identification of potential failure mechanisms is based on …

Alkali–aggregate reaction (AAR) in concrete has been found to cause serious concerns for
the operation and integrity of many mass and reinforced concrete structures, hydraulic …

This work aims to fill the gap between experimentation on laboratory specimens and
structural diagnosis of mass concrete hydraulic structures affected by alkali-aggregate …

Using steel fibres as primary reinforcement in structural elements requires design methods
based on meaningful material properties and good construction practices. In the recent …

L'amélioration continuelle des connaissances sur la sismicité et la réponse dynamique des
structures au courant des dernières années a révélé la présence de certaines lacunes dans …

Plusieurs structures de béton dans le monde sont sujettes à des dégradations accélérées
dues à la réaction alcali-granulats (RAG). Lorsqu'elle se développe, cette réaction chimique …

Using ultrahigh-performance fibre-reinforced concrete (UHPFRC) for reinforcement lap
splice field connections simplifies construction details, reduces on site labour work and …
