Experimental and numerical analysis of flexural composite beams with partial use of high strength/high performance concrete

The paper summarises the experimental and numerical analysis of flexural capacity and deformability of structural concrete beams prepared as composite members consisting of two concrete layers made of reinforced normal concrete and highâ€performance concrete (HPC). The reinforced concrete compos...
