The project has fully achieved its objectives and milestones for the period. The following objectives as described in the DoA have been fulfilled: (i) To investigate the deformation characteristics of FRP-RC members experimentally by testing FRP-RC specimens of different structural configurations subjected to different loading conditions; (ii) To derive constitutive theory and models of FRP-RC including bond, tension stiffening, tension softening, cracking behaviour, fracture mechanics and the time-dependent effects on the above; and to establish deformation capacity of FRP-RC members; and (iii) To formulate simplified design guidelines in serviceability and develop design aids of FRP-RC structures for use by practising engineers.
Regarding objective (i), FRP-RC beams of different tension reinforcement ratios were tested. The test results provided a basis for assessing the crack behaviour and post-cracking stiffness and response of FRP-RC beams of different structural configurations.
Regarding objective (ii), constitutive models for FRP-RC members were developed and included in computational models for rigorous numerical analysis. The results were verified against experimental results. This set out the comparative basis for verifying the simplified design approach.
Regarding objective (iii), dedicated design guidelines for serviceability of FRP-RC flexural member were drawn up from the study. The accuracy was verified by across comparison with experimental and analytical results. Design aid in spreadsheet format for FRP-RC beams was developed.
Throughout the action, the planned training and two-way transfer of knowledge between the researcher and the host were satisfactorily achieved.
