EXPERIMENTAL INVESTIGATION OF THE STRUCTURAL BEHAVIOUR OF ECC LINK SLABS REINFORCED WITH FRP
With the increasing traffic loading and large variation of environmental temperatures,deteriorations of expansion joints between simply supported spans cause repeated structural maintenance and high repair costs.The focus of this study is to study the behaviour of a link slab element,which can be used as a joint between two adjacent structural components.In this joint system,a ductile Engineering Cementations Composites(ECC)link slab reinforced with Fiber Reinforced Polymer(FRP)grid is proposed for replacing the conventional expansion joint.The requirements on the link slab include material properties and reinforcement with FRP.This research herein describes the study of mechanical performance of ECC specimens.Subsequently,the test results of the flexural behaviour of reinforced ECC test specimens were presented and discussed.It was shown the ductility and multiple cracking behaviour of ECC.Thereafter,a series of this ECC link slab specimens positioned in concrete deck structures was built and tested to investigate the behaviour of this novel component.
