Dynamic interfacial bond behaviour between basalt fiber reinforced polymer sheets and concrete

Dynamic interfacial bond behaviour between basalt fiber reinforced polymer sheets and concrete

An experimental investigation on the dynamic interfacial bond behaviour between basalt fibre (BFRP) sheets and concrete under different loading speeds (i.e. 8.33E−6 m/s, 0.1 m/s, 1 m/s, 3 m/s, 5 m/s, and 8 m/s) by using single-lap shear tests was carried out in this study. Experimental results inclu...

Description
Summary:An experimental investigation on the dynamic interfacial bond behaviour between basalt fibre (BFRP) sheets and concrete under different loading speeds (i.e. 8.33E−6 m/s, 0.1 m/s, 1 m/s, 3 m/s, 5 m/s, and 8 m/s) by using single-lap shear tests was carried out in this study. Experimental results including bond strength, strain time histories, strain distributions in the bonding areas, interfacial fracture energy, and bond-slip curves are presented in this study. The test results show that the interface is strain rate dependent. The interfacial fracture energy, bond strength, and interfacial bond shear stress-slip are sensitive to strain rate. Empirical bond-slip model including strain rate effect are established for the predictions of bond properties between BFRP sheets and concrete under dynamic loading.
