This study examines the cyclic behaviour of square steel tubes infilled with rubberised alkali-activated concrete. The concrete is made up of a slag-based mix activated with solid anhydrous sodium metasilicate. The rubber content, as replacement of natural aggregates, is varied up to a high replacement ratio of 60%. Specimens are tested under lateral cyclic loading with a co-existing axial load of 15 and 20% of the cross-sectional axial capacity. A detailed account of the cyclic tests is given, covering 8 concrete-filled steel specimens and 2 hollow steel specimens. Complementary material and section tests are also provided.

The experimental results are discussed in detail covering the member stiffness, displacement, capacity, ductility, energy dissipation and failure mechanisms.

The Society for Earthquake and Civil Engineering Dynamics Young Members (SECED YM) AGM will take place before the lecture.

Mohamed El-Zeadani

Mohamed El-Zeadani is a PhD student in the Department of Civil and Environmental Engineering at Imperial College London. His PhD research is focused on the mechanical and structural behaviour of rubberised alkali-activated concrete, including the material characterisation and structural response under cyclic loading conditions. His technical interests involve developments in sustainable concrete materials, numerical modelling, and mechanics-based solutions for concrete structures under various loading conditions.
