Numerical dynamic characterisation of concrete bridge stays
Earthquake Engineering &Structural Dynamics, Volume 52, Issue 14, Page 4466-4488, November 2023., 2023 Abstract Following the recent collapse of a cable‐stayed bridge in Genoa, Italy, an interest has arisen to understand if it would have been possible for unknown localised material deterioration and/or decrease in prestress levels to introduce noticeable changes in the dynamic behaviour of RC stays.

Three‐dimensional testing of fasteners
Structural Concrete, Volume 24, Issue 2, Page 2623-2637, April 2023., 2023 Abstract Experimental results of tests to investigate the load‐bearing behavior of anchor channels embedded in concrete and subjected to loads in three‐dimensional (3D) interaction are presented. For testing, a variably adjustable rig is introduced in which arbitrary 3D loads are applied with just one hydraulic cylinder.

Study on collapse mechanism of steel frame with CFST-columns under column-removal scenario [PDF]
, 2018 The design of structure against progressive collapse has tended towards more quantitative design where utilizing catenary action becomes essential. In this paper, a single internal column removal test was conducted for a 1/3 scale 4-bay steel frame with ...
