Beam tests for the determination of the interfacial properties of FRCM composites

Fiber Reinforced Cementitious Matrix (FRCM) materials are widely used for strengthening reinforced concrete (RC) structures. Experimental studies show that the collapse of RC elements with FRCM composites occurs due to loss bond reinforcing material. For this reason issue shear stress transfer between reinforcement and substrate has been extensively studied in last years. The single-lap test is most frequently adopted configuration. In paper results tests a composite performed beam configuration presented. determine cohesive material law (CML) tested obtained CML compared on basis tests. comparison shows two configurations provide similar CML.
