TL;DR: In this paper, the development of the family of concrete-filled steel tubular structures to date and drawing a research framework on CFST members is reviewed and discussed, and the current design approaches from various countries are examined briefly.
940 citations
TL;DR: In this article, a finite element analysis (FEA) of concrete-filled thin-walled steel tubes subjected to pure torsion is used to investigate the influence of important parameters that determine the ultimate torsional strength.
Abstract: In practice, concrete-filled steel tubes (CFST) are often subjected to torsion. To date, such a problem however has not been addressed satisfactorily by design codes. The present study is thus an attempt to study the torsional behaviours of concrete-filled thin-walled steel tubes. ABAQUS software is used in this paper for the finite element analysis (FEA) of CFST subjected to pure torsion. A comparison of results calculated using this modelling shows good agreement with test results. The FEA modelling was used to investigate the influence of important parameters that determine the ultimate torsional strength of the composite sections. The parametric studies provide information for the development of formulae to calculate the ultimate torsional strength, as well as the torsional moment versus torsional strain curves of the composite sections.

TL;DR: In this paper, the authors investigated the behavior of self-consolidating concrete (SCC) filled hollow structural steel (HSS) stub columns subjected to an axial load.
422 citations
TL;DR: In this paper, the behavior of stub columns of concrete-filled rectangular hollow sections (RHS) subjected to axial load was investigated experimentally, and the main objectives of these tests were to describe a series of tests on composite columns; and secondly, to analyze the influence of several parameters such as constraining factor and width ratio on the behaviour of RHS columns.

TL;DR: In this paper, a unified theory is described where a confinement factor (ξ) is introduced to describe the composite action between the outer steel tube and the sandwiched concrete, and simplified models are derived to predict the load-carrying capacities of the composite members.

TL;DR: The properties of concrete is universally compatible with any devices to read, and is available in the digital library an online access to it is set as public so you can download it instantly.
Abstract: Thank you for downloading properties of concrete. As you may know, people have look hundreds times for their chosen readings like this properties of concrete, but end up in malicious downloads. Rather than reading a good book with a cup of coffee in the afternoon, instead they juggled with some malicious virus inside their computer. properties of concrete is available in our digital library an online access to it is set as public so you can download it instantly. Our digital library hosts in multiple locations, allowing you to get the most less latency time to download any of our books like this one. Merely said, the properties of concrete is universally compatible with any devices to read.
