Abstract ：
Circular concrete-filled double steel tubular (CFDST) column is a high-performance composite column that has significant potential to be used in the construction of high-rise composite structures. This paper presents experimental and strength computational investigations on CFDST short columns that are subjected to eccentric compression load. A total of sixteen CFDST stub columns, two concrete-filled steel tubular (CFST) columns, and two double-skin concrete-filled steel tubular (DCFST) columns were tested to investigate their structural performance. The test behavior of the CFDST column loaded eccentrically is discussed and compared against its CFST and DCFST counterparts. The test results show that the CFDST column has improved strength and ductility under eccentric loading when compared with other composite columns. The strengths of the CFDST stub columns in this study together with the test strengths from the literature were used to assess the strength predictions by Eurocode 4 and AISC 360-16. It was found that the current predictions generally underestimate or overestimate the strengths. A new reduction factor for predicting the ultimate strengths of CFDST short columns under eccentric compression is proposed based on the test results. By adopting the newly proposed reduction factor and design method, the design predictions are found to be improved that provide reasonable estimations for circular CFDST columns loaded eccentrically.

Abstract ：
Shear walls of cold-formed steel (CFS) with high aspect ratios could be used in buildings with large openings such as doors and windows. However, the performance of CFS shear walls with high aspect ratios remains unclear due to limited test data. This research aimed to explore the mechanic performance and strength reduction factor of CFS shear walls with high aspect ratios through an experimental study. Five full-scale specimens were tested under monotonic loading, and the failure mechanism, bearing capacity, stiffness, ductility, and energy dissipation of the specimens were obtained. The test results indicated that shear walls with small aspect ratios typically fail as a result of connection damage to horizontal seams and corners, whilst shear walls with high aspect ratios commonly buckle at both the end stud and bottom track. As the aspect ratio increased, the initial stiffness and capacity decreased, while the energy dissipation per unit length increased due to greater flexibility. Ultimately, this study proposes a more reasonable design formula for strength reduction factors based upon a regression analysis of the test data. This will facilitate a more sustainable design approach, and fulfills current standards in engineering practice.

Abstract ：
The accurate prediction of the concrete confinement effects in concrete-filled double-skin steel tubular (CFDST) columns composed of a circular section is vital in stimulating their true structural performance. However, existing concrete confinement models for such columns were developed based on limited studies and may not accurately predict their axial responses under axial loading. In this paper, a numerical model is developed to study the nonlinear performance of axially-loaded short CFDST columns incorporating an accurate concrete confinement model. Herein, a novel expression to calculate the lateral confining pressure on the confined concrete of the CFDST column is proposed considering the influences of a wide range of important column parameters. Furthermore, a reduction factor to accurately predict the post-peak behavior of confined concrete is suggested based on the previous test results. The accuracy of the numerical model incorporating the proposed concrete confinement model is verified against the experimental tests. The accuracy of the existing concrete confinement models is also evaluated and compared with the one proposed in this study. It is demonstrated that the proposed confinement model can yield the axial performance of CFDST columns more accurately. A parameter study is then performed to analyze the impacts of important column parameters on the axial performance of such a column. The applicability of the existing design standards in designing CFDST columns is verified. Lastly, a simple and accurate design equation to quantify the ultimate axial load is proposed.

Abstract ：
This article investigates the axial compressive performance of concrete-filled double steel tubular (CFDST) short columns composed of circular section loaded concentrically. An experimental program comprised of compression tests on short columns is carried out to examine their structural performance. Axial compression tests on conventional concrete-filled steel tubular (CFST) columns and double-skin concrete-filled steel tubular (DCFST) columns are also performed for comparison purposes. The test parameters include the diameter-to-thickness of the outer and inner steel tubes, concrete strength, and diameter ratio. The test results exhibit that CFDST short columns composed of the circular section have improved structural performance compared to its CFST and DCFST counterparts. A theoretical model is also presented to simulate the test ultimate strengths and load-axial strain relationships of CFDST columns. The existing design models proposed including the codified design specifications are evaluated against the collected test data for predicting the axial compressive strengths of circular CFDST columns. It is seen that the existing codified design models cannot yield their ultimate axial compressive strengths accurately. A practical artificial neural network (ANN) model is proposed to estimate the ultimate load of such columns loaded concentrically.

Abstract ：
In this paper, the structural behavior of concrete-filled double steel tubular (CFDST) stub columns composed of square hollow sections is investigated experimentally and numerically. The experimental program comprises compression tests on short columns loaded concentrically. The test parameters mainly focused on the influences of the width-to-thickness ratios of steel tubes and concrete strength on the axial behavior of CFDST stub columns. Finite element (FE) models are also developed to investigate the influences of a wide range of structural parameters on their axial performance. It is observed that square CFDST columns have improved strength and ductility compared to their CFST and DCFST counterparts. Finally, a calculation formula is proposed to predict their ultimate compressive strengths under the axial compression load.
