The application of stainless steel tubes in concrete-filled tube systems can significantly improve their corrosion resistance comparison with those that employ carbon tubes. In this paper, a series push-out tests were carried out to investigate the bond stress-slip behavior between and concrete. A total 14 square specimens tested, covering two cross-sectional width-thickness ratios (B/t = 30 50...

Aluminum foam has received considerable attention in various fields and is expected to be used as an engineering material owing to its high energy absorption properties and light weight. To improve the mechanical properties of aluminum foam, combining it with dense tubes, such as aluminum foam-filled tubes, was considered necessary. In this study, an aluminum foam-filled steel tube, which consi...

Stringently anaerobic bacteria have been successfully cultured in rubber-stoppered roll tubes. Stoppers of certain types of rubber are so permeable to oxygen that they are unsuitable (Hungate, J. Bacteriol. 86:848, 1963). Butyl rubber is less permeable to gases than are many other types. The permeabilities of butyl stoppers and a common laboratory type to gases concerned in anaerobic culture wo...

The traditional quality detection method for transparent Nonel tubes relies on human vision, which is inefficient and susceptible to subjective factors. Especially for Nonel tubes filled with the explosive, missed defects would lead to potential danger in blasting engineering. The factors affecting the quality of Nonel tubes mainly include the uniformity of explosive filling and the external di...

In this paper, the eccentric compression test of seven specimens was conducted to explore application possibility recycled aggregate concrete (RAC) in L-shaped columns composed concrete-filled steel tubes (CFST). The main parameter is replacement ratio coarse aggregates (RCA), and an column hollow set as a control. results indicated that bearing capacity stiffness RAC-filled (RACFSTs) are bette...

Our research investigated the energy absorption characteristics of chiral auxetic lattices filled cylindrical composite tubes subjected to a uniaxial and lateral quasi-static load. The lattice structures were manufactured using 3D printing technique. Carbon fiber without filler material initially crushing same types experiment then performed on tubes. For different cases, load–displacements cur...
