High‐Performance Pre‐engineered Steel‐Concrete Composite Beams for Sustainable Construction – Mechanical Behaviour of the Full‐Scale Beams
This paper presents an experimental study on the behaviour of high‐performance pre‐engineered steel‐concrete composite beams. The slab is constructed with green concrete of grade C55/67 made using recycled concrete aggregates to replace 20% of natural aggregates, and GGBS together with silica fume as supplementary ce‐mentitious materials to replace 25% of the Ordinary Portland Cement (OPC). Pre‐engineered (built‐up) structural steel asymmetric section of grade S460M is adopted for optimised structural efficiency. To verify the compatibility among the three different materials used, i.e., the S460M structural steel, green C55/67 concrete, and the shear studs, shear connection specimens were designed and tested with reference made to EC4. Subsequently, 2 full scale steel concrete composite beams are tested until failure. The results showed that the EC4 design equations for predicting the shear resistance and the bending moment resistance are still conservative for the materials and full‐scale beams.
