  • Axial Capacity and crushing behavior of metal fiber square tubes steel stainless steel and aluminum with cfrp
    Composites Part B-engineering, 2010
    Co-Authors: Michael Richard Bambach

    Abstract:

    Abstract Composite metal-carbon fiber reinforced polymer (CFRP) tubes combine the benefits of the high strength to weight ratio of the fiber/resin composite and the stable, ductile plastic collapse mechanism of the metal, to form a composite tube with high strength and energy absorption capability. This paper investigates the Axial Capacity and crushing behavior of square hollow section (SHS) tubes composed of composite steel-CFRP, stainless steel-CFRP and aluminum-CFRP. Experiments of tubes with different metal SHS geometries and two different matrix layouts of carbon fibers are described, and a general theory to predict the compression buckling, Axial Capacity, Axial collapse and mean crush load of metal–fiber square tubes is developed and validated against the experimental results. It is shown that carbon fiber may be successfully externally bonded to metal SHS, and such application may be provided to improve the performance of existing structures, or to design new structures with enhanced strength-weight and energy absorption-weight ratios. Comparisons are made between the performance of the different types of metals, SHS geometries and carbon fiber matrix layouts.

  • Axial Capacity and crushing of thin-walled metal, fibre–epoxy and composite metal–fibre tubes
    Thin-walled Structures, 2010
    Co-Authors: Michael Richard Bambach

    Abstract:

    Abstract Recent investigations of square hollow section (SHS) metal tubes with externally bonded carbon fibres have shown significant increases in the Axial Capacity and mean crushing load, compared with the metal SHS. The composite metal–fibre tubes employed carbon fibre reinforced polymer (CFRP) matrix layouts of two and four layers of carbon fibres. In this paper the same sized two and four layer CFRP SHS were manufactured independent of the metal SHS, and the Axial Capacity and crushing behaviour were determined experimentally. Four different tube sizes were tested, resulting in tube width to thickness ratios between 32 and 144. A photogrammetry system was employed to accurately determine the buckling and post-buckling behaviour. It is shown that the Capacity and mean crush load of the composite metal–CFRP SHS exceed the sum of those for the individual metal SHS and CFRP SHS, by up to 1.8 times. This composite action results from the bond between the metal and the carbon fibres, and the mechanics with respect to buckling, Capacity and crushing is discussed. The strength of metal, composite metal–CFRP and CFRP tube walls are determined using the effective width approach, and are shown to compare well with the experimental results.

  • Axial Capacity of rectangular concrete filled steel tube columns doe approach
    Construction and Building Materials, 2010
    Co-Authors: Manojkumar V Chitawadagi, Mattur C Narasimhan, S M Kulkarni

    Abstract:

    Abstract This paper presents the effect of change in wall thickness of the steel tube ( t ), strength of in-filled concrete ( f cu ), cross-sectional area of the steel tube ( A ) and length of the tube ( L ) on ultimate Axial load and Axial shortening at ultimate point of rectangular concrete-filled steel tubes (CFT). Taguchi’s approach with an L9 orthogonal array is used to reduce the number of experiments. With the help of initial experiments, linear regression models are developed to predict the ultimate Axial load and the Axial shortening at ultimate point. A total of 243 rectangular CFT samples are tested to verify the accuracy of these models at three factors with three levels. The experimental results are analyzed using Analysis Of Variance to investigate the most influencing factor on strength and Axial shortening of CFT samples. Comparisons are made with predicted column strengths using the existing design codes, AISC–LRFD-1994 and EC4-1994.
