“…Other researchers have investigated the application of sustainable material, such as recycled-aggregate, in the concrete infill [13,14]. Only limited research has been conducted on the structural response of composite steel-timber systems [15][16][17][18][19][20] and even less on confined timber or timber filled steel tubular columns (TFST) [21][22][23]. Najm et al [21] performed compressive tests on circular timber columns confined with carbon fibres.…”

“…During the past 10 years, Ghanbari Ghazijahani and his colleagues conducted many experiments on cylindrical tanks. Most of their experiments focused on the imbalance created on shells and the buckling effects on these shells 19‐23 . Ghanbari Ghazijahani and his colleagues also examined the effects of localized dents on thin‐walled structures 24 .…”

[19][20][21][22][23] Ghanbari Ghazijahani and his colleagues also examined the effects of localized dents on thin-walled structures. 24 Moreover, the thermal buckling of cylindrical shells under uniform heating and temperature gradients through the thickness was studied in the past, [25][26][27][28][29] but the thermal loading generated by a fire is more complicated than these patterns.…”

Thin-walled shell structures are characterized by a lightweight structural form with high strength. This structure has many applications in various engineering fields and is considered to be a basic tool in the modern industry. This study investigates the effect of CFRP on tanks after post-fire in order to examine the buckling and postbuckling of the cylindrical tanks. Herein, post-fire was introduced at different temperatures (150 C-600 C). Ten laboratory specimens in two groups with verified temperatures, under external pressure, are examined. The models were designed to demonstrate how repairing steel tanks, which are damaged by fire, by using carbonfiber-reinforced polymer can recover lost capacity. The results of testing under different theories and codes were compared. This study shows that the initial buckling load of the temperature group increased by 30.82% to 57.09% compared to the temperature without-CFRP group. The overall buckling load of the temperature group increased by 37.01% to 67.74% compared to the temperature without-CFRP group. The collapse load of the temperature group increased by 27.04% to 52.64% compared to the temperature without-CFRP group. And using carbon-fiber-reinforced polymer on models, which are damaged by fire, can be an improvement behavior for the buckling and post-buckling specimen tests.

“…In recent years, a few studies have been carried out on concrete-filled double-skin steel tubular columns (Elchalakani et al, 2002; Farahi et al, 2016; Hassan et al, 2016; Hassanein et al, 2015; Imani et al, 2015; Pagoulatou et al, 2014; Uenaka et al, 2010; Zhao et al, 2002). Another form of composite members for the purpose of weight reduction has been proposed by Ghazijahani et al (2015, 2017).…”

Experimental and numerical investigations of concrete-filled double-skin aluminium stub column with a circular hollow section as the outer skin and a square hollow section as the inner skin are presented in this article. A test program was carried out to study the influences of aluminium tube geometric dimensions and concrete strength on structural performance and strength of composite columns. A series of composite columns was tested on outer circular hollow section tubes and inner square hollow section tubes; the spaces between them had been filled with concrete of different nominal cylinder strengths of 40, 70 and 100 MPa. The tubes were fabricated by extrusion using 6061T6 heat-treated aluminium alloy having a nominal 0.2% proof stress of 240 MPa. A non-linear finite element model was developed and verified against experimental results. The test and numerical results were compared with the design strengths to evaluate the applicability of the design rules in the American specifications for aluminium and concrete structures. In addition, the proposed design equations, developed by the authors for concrete-filled double-skin aluminium tubular stub columns with circular hollow section as both outer and inner skins, were used to calculate the design strengths and compared with the experimental and numerical results obtained in this study. The proposed design equations also predicted the ultimate strengths of the concrete-filled double-skin aluminium tubular stub columns accurately with circular hollow section as the outer skin and square hollow section as the inner skin.
