Abstract
ABSTRACT This study presents the structural behaviour of tyre-bale sandwich wall under four-point bending and punching shear load. The research entails two stages: (a) full-scale experimental testing and (b) and numerical analysis of a 3D finite element modelling (FEM). In the first stage, two tyre-bale sandwich walls are tested experimentally in flexural bending to investigate the structural behaviour in terms of ultimate load, vertical deflection, strain distribution on the concrete surface, deflected profile, crack pattern and tyre-bale compressibility. The second stage consisted of three phases: (a) validation of the material model and assembly of different parts by comparing load-deflection curve and concrete damage in tension, (b) calibration of punching shear load and boundary conditions using previous experimental research data and (c) study ultimate load and failure mode under punching shear in tyre-bale sandwich wall. The results of the proposed 3D FEM model showed good agreement with experimental work and predicted the failure mechanism with reasonable accuracy. The calibrated model can be used to further investigate the factors affecting the structural behaviour of tyre-bale sandwich walls under different loading conditions. Finally, the strength of reinforced concrete member was confirmed using yield line theory, which showed a fair agreement with the experimental values.
期刊介绍：
The Australian Journal of Structural Engineering (AJSE) is published under the auspices of the Structural College Board of Engineers Australia. It fulfils part of the Board''s mission for Continuing Professional Development. The journal also offers a means for exchange and interaction of scientific and professional issues and technical developments. The journal is open to members and non-members of Engineers Australia. Original papers on research and development (Technical Papers) and professional matters and achievements (Professional Papers) in all areas relevant to the science, art and practice of structural engineering are considered for possible publication. All papers and technical notes are peer-reviewed. The fundamental criterion for acceptance for publication is the intellectual and professional value of the contribution. Occasionally, papers previously published in essentially the same form elsewhere may be considered for publication. In this case acknowledgement to prior publication must be included in a footnote on page one of the manuscript. These papers are peer-reviewed as new submissions. The length of acceptable contributions typically should not exceed 4,000 to 5,000 word equivalents. Longer manuscripts may be considered at the discretion of the Editor. Technical Notes typically should not exceed about 1,000 word equivalents. Discussions on a Paper or Note published in the AJSE are welcomed. Discussions must address significant matters related to the content of a Paper or Technical Note and may include supplementary and critical comments and questions regarding content.
