“…The failure mode is governed by the fracturing of FRP wrapping and local buckling of stainless steel tubes. Owing to the high ductility of stainless steel, a high residual load bearing capacity is still present after the failure [16,53]. The stress-strain curve of an FRP-wrapped stainless-steel-filled SWSSC column is also similar to that of FRP-confined carbon-steel-filled SWSSC columns with four stages [16,57].…”

The environmental concerns raised by the over-exploitation of fresh water and river sand have driven researchers to explore seawater sea sand concrete (SWSSC) as a substitute for conventional concrete in structural columns. With numerous investigations on this in the past, there is a need to systematically classify and comprehensively understand the response of confined SWSSC columns to promote their usage as structural columns. Consequently, the objective of this review is to summarise and analyse the experimental work conducted so far on confined SWSSC under different compressive loadings. Confined SWSSC columns are classified into five confinement schemes based on the cross-section of the specimens: single-skin, single-skin multilayered, single-skin with additional reinforcement, double-skin, and double-tube-confined SWSSC columns. Based on the findings of the reviewed studies, it can be concluded that the compressive strength and the ductility of the SWSSC can be enhanced through confinement, with effectiveness majorly depending on the material and geometrical properties of the confinement providing material. The existing research work on SWSSC confinement lays out a strong base for future investigations in this area, which will eventually facilitate the acceptance of SWSSC as structural columns, especially for coastal and marine infrastructure.

“…The structural behaviors of an FRP-concrete-steel double-skin tubular column subjected to axial compression [9][10][11][12] and bending load [13,14] have been investigated. Liao et al [10] examined the axial compressive behavior of an FRP-confined seawater sea-sand concrete-filled stainless steel tubular column. Zhang et al [13] studied the flexural elastic modulus of the steel tube, tested in accordance with GB/T228.1-2010 [38] and GB/T 2975-2018 [39], were 430 MPa and 206.2 GPa, respectively.…”

“…However, considering the reliable beam–column connection, square columns [ 16 , 31 ] are being given more attention than circular columns in some structures. Moreover, the existing research mainly focused on the axial compression [ 4 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 19 , 22 , 32 , 33 ] and seismic performance [ 15 , 16 , 20 , 21 ] of columns. The findings regarding the compression and bending performance of hollow-core square columns are still limited, which has impeded the application of this new structure in engineering.…”

Eccentric Compression Properties of FRP–Concrete–Steel Double-Skin Square Tubular Columns

et al. 2023

FRP (fiber-reinforced polymer)–concrete–steel double-skin square tubular (FCSST) columns are composed of an outside FRP tube, an inside steel tube and the concrete filled between them. Under the continuous constraint of the outside and inside tube, the strain, strength and ductility of concrete are improved significantly compared with those of traditionally reinforced concrete without lateral restraint. Additionally, the outside and inside tube not only function as the permanent formwork in casting but improve the bending and shear resistance of composite columns. Meanwhile, the hollow core also reduces the weight of the structure. Through the compressive testing of 19 FCSST columns subjected to eccentric load, this study focuses on the influence of eccentricity and layers of axial FRP cloth (away from the loading point) on the evolution of axial strain along the cross-section, axial bearing capacity, axial load–lateral deflection curve and other eccentric properties. The results can provide basis and reference for the design and construction of FCSST columns and are of great theoretical significance and practical value for the application of composite columns in the engineering of structures in a corrosive environment and other harsh conditions.

The increasing demand for river sand, driven by infrastructure development, poses environmental challenges. The study aims to address the depletion of river sand by integrating sea sand as a fine aggregate in the production of Self-Compacting Concrete (SCC) through a Systematic Literature Review. Furthermore, it includes an in-depth bibliographic analysis of relevant literature using VOSviewer to generate network visualizations of author-co-citation and country-wise citations. The article offers diverse options for sustainable solutions to mitigate environmental impacts while meeting infrastructure demands. It focuses on assessing the durability of SCC incorporating sea sand through real-time monitoring with the Internet of Things (IoT) and employing artificial intelligence methods like PointRend and neural networks to study the properties of SCC utilizing sea sand. Subsequently, the study emphasizes the need to address river sand shortages in infrastructure development and provides insights for further research on enhancing the properties of SCC with sea sand.
