High-performance ferrocement laminate(HPFL) is a new method to reinforce RC component.It adopts HPFL as inorganic material,and possesses numerous merits.In order to study the shear pins' impact on the interfacial bonding properties at high-temperatures,the test include 6 RC beams strengthened with U-shaped HPFL (ferrocement was put onto the tension face and two profile faces) and 1 reference RC beam.All the beams strengthened with U-shaped HPFL are divided into three groups.The two beams strengthened with U-shaped HPFL in the first group without implanting shear pins.However,the two beams strengthened with U-shaped HPFL in the second group with shear pins by larger spacing.And the last two beams strengthened with U-shaped HPFL in the third group are also implanted with shear pins by smaller spacing.After the test,there is a comparison of their duration of fire resistance,deflection and destruction mode,and an analysis of the interface's failure mechanism is done at high-temperature.The results show that the implanted shear pin can significantly improve the interfacial bonding properties at high-temperature,and the strengthened beams' fire resistance at high-temperature has been greatly improved.
