In this study, 11 PSRPC column specimens were designed and fabricated in order to investigate the stressing performance of incompletely prefabricated steel reactive powder concrete (PSRPC) columns subjected static loading tests. The effects strength grade content (RPC) on axial compression eccentricity investigated. test results show that external RPC, internal section cast-in-place RPC work we...

The axial compression strength of concrete columns has been proved to be significantly enhanced by external confinement. In this perspective, the use Fiber-Reinforced Polymers (FRPs) extensively studied. practical applications, FRP-confinement is installed on loaded columns, which can already deformed, while theoretical models neglect aspect. This paper concerns a new experimental investigation...

Cylindrical shell is a fundamental building block of many engineering structures. They are usually designed to be the primary load-carrying components withstand different combinations environmental loads. This paper presents fibre-based approach modelling progressive collapse cylindrical shells under combined axial compression and bending moment. In this method, behaviour incrementally evaluate...

Abstract The addition of nano-silica to ultra-high-performance concrete (UHPC) increase its toughness has been proposed obtain nano-concrete (UHPNC). This work mainly studies the reinforcement effect UHPNC on filled steel tube (CFST) columns under long-term load. Ten CFST strengthened with were selected and reinforced UHPNC. influences different thicknesses layer contents axial compression prop...

In this paper, a CT based structural rigidity analysis (CTRA) method that incorporates bone intrinsic local curvature is introduced to assess the compressive failure load of human femur with simulated lytic defects. The proposed CTRA is based on a three dimensional curved beam theory to obtain critical stresses within the human femur model. To test the proposed method, ten human cadaveric femur...

The majority of columns are subjected to a combination of an axial load and a bending moment in one or two directions. With a few exceptions, most of the research in the area of FRP wrapped columns have concentrated on the behaviour of concentrically loaded columns. This paper presents results of testing nine reinforced high strength concrete columns. The column specimens are circular in shape ...
