Structural behaviour of Ultra-High Performance Fibre Reinforced Concrete Columns subjected to eccentric loading

摘要

An experimental investigation conducted on ultra-high performance fibre reinforced concretern(UHPFRC) columns is presented in this paper. The columns consisted of longitudinal and transversernreinforcement, tested under concentric and eccentric compressive loads with varying loadrneccentricities. The UHPFRC manufactured with locally available raw materials attainedrncompressive strengths of 140 to 160MPa. The experimental data of axial load with lateral and axialrndeformations, mode of failure was obtained for each test. The cover spalling was not observed forrnall the columns. The interaction diagram of axial load-bending moment is established forrncompression members and is in good agreement with the test results.
