A program has been developed to utilise the Particle Swarm Optimisation Algorithm for the cost optimum design of reinforced concrete beams. Multiple constraints according to Australian Standard 3600 have been implemented along with costing information. A series of tests where conducted to investigate the effect of different parameters of the particle swarm algorithm and some refinement of these parameters was conducted. The value penalty coefficients had a significant effect on the results, causing non-convergence when very large penalty coefficients where used, and convergence on non-viable results when very small penalty coefficients where used.

Fibre-reinforced polymer (FRP) jackets have been widely used to confine concrete columns to enhance their load-carrying capacity and ductility. More recently, the use of FRP jackets to improve the performance of hollow steel tubes and concrete-filled steel tubes has also been explored. This paper presents the results of a recent experimental study in which the behaviour of FRP-confined circular concrete-filled thin steel tubes under axial compression was examined. The experimental study included three series of tests and was focussed on the effects of the diameter-to-thickness ratio of the steel tube and the confinement stiffness of the FRP jacket. The test …

This paper presents results of testing 16 specimens, 12 of which as columns under different eccentricitiesand four as beams under four point loading regime. All 16 specimens were circular in cross section andwere made of reinforced concrete. Four specimens served as reference specimens and were just made ofreinforced concrete. The next four specimens were wrapped with carbon fibre reinforced polymers(CFRP). The next four specimens had steel fibres added to the concrete. The final four specimens werereinforced with steel fibres and wrapped with CFRP. From each group of specimens, one specimen wastested as a column under a concentric load, the second …
