On Tuesday 24 October at 2.30 pm in Grandori Room (Building 4 – p.za Leonardo da Vinci, 32 – Milan) a seminar entitled: “Recycled Aggregate Concrete Composite Structures” will be held by Huan Zhang, Associate Professor of Structural Engineering at the School of Civil Engineering at Harbin Institute of Technology, China.

Abstract 

Natural sand and stone resources are depleting rapidly, and there is an urgent need to optimize the disposal methods for waste concrete. Recycled aggregate concrete (RAC) provides an effective solution to address these challenges. Steel-concrete composite structures can fully leverage the properties of materials, compensating for the lower mechanical performance and higher discrepancies of RAC. The establishment of RAC mechanical properties models and the development of design method for steel-RAC composite structures is crucial for promoting the structural application of RAC. This presentation will delve into the influence mechanism of recycled aggregates, discussing key issues in the development of mechanical property models for RAC and design methods for steel-RAC composite structures. Finally, this presentation will introduce the proposed models for mechanical properties of RAC and design methods for RAC filled steel tubes and steel-RAC composite slab/beam systems, addressing both load-carrying capacity and long-term performances.
