FRP Strains in FRP Wrapped Columns
, 2007 Extensive research has been undertaken on strengthening concrete columns using FRP wraps. Recent research has extended this technique into strengthening steel tubular and concrete filled steel tubular columns. The behaviour of FRP confined concrete columns is now well understood and accurate models for both design and analysis are available.

Nordic Journal of Botany, EarlyView.Phyllanthus asteranthos Croizat has been treated as a synonym of P. pulcher Wall. ex Müll. Arg. (syn. Nymphanthus glaucescens (Miq.) R.W.Bouman) since 1987. Through detailed morphological observations of living plants and critical examinations of type materials and additional specimens, this study revealed that the two taxa are morphologically very ...

Oikos, EarlyView.Annual survival is a key demographic parameter driving population trends in wildlife populations. However, despite numerous species‐specific or regional studies, global reviews of the factors affecting the survival of declining taxa remain scarce. Here, we investigated annual survival of fledged immature and adult shorebirds, a globally‐distributed and

Predictive Assessment of Progressive Damage in Mechanically Fastened Glass–Epoxy Composites
Polymer Composites, EarlyView.Progressive damage in mechanically fastened glass–epoxy composites. ABSTRACT Ensuring the structural integrity of advanced composites necessitates precise methodologies for forecasting the onset and progression of damage. This research focused on the predicting progressive damage (PD) for riveted joints composite laminates employing a combined ...
