Special Issue Information

Dear Colleagues,

The development of high-performance materials, e.g., high-strength steel and high-performance concrete, provides more alternatives to develop high-performance steel–concrete composite structures. This issue aims to incorporate the state-of-the-art developments of steel–concrete composite structures using these new high-performance materials, e.g., high-strength steel, weathering steel, high strength concrete, fiber-reinforced concrete, green concrete, lightweight concrete, recycled concrete, etc. Moreover, the applications of steel–concrete composite structures in mega projects are especially preferred, e.g., high-speed train bridges, long-span bridges, immersed tunnels, offshore structures, and tunnels.  

Including the developments and experimental studies on these high-performance steel–concrete composite structures, new theory and numerical methods on analyzing or simulating static, dynamic, or seismic responses of these high-performance steel–concrete composite structures are also included in this issue.

The excellent seismic performance of concrete-filled steel tube (CFST) structures has been widely recognized, but there is a paucity of research on composite columns using UHPC with added steel fibers. This paper presents the experimental studies and numerical analyses with OpenSees on seismic performance of ultra-high performance steel fiber-reinforced concrete (UHPSFRC)-filled square steel tubular columns. Five half-scaled specimens of UHPSFRC-filled square steel tubular columns were tested under a combination of constant axial compression and cyclic horizontal load, with parameters of width-to-thickness ratio (28.5, 19.9 and 14.7) and axial compression ratio (0.133, 0.266 and 0.399) of the steel tube. With the decrease in width-to-thickness ratio, the maximum bending moment capacity increased by 33.5% and 15.3%, and the energy dissipation capacity and ductility increased, while the strength degradation and stiffness degradation reduced. With the increased axial compression ratio, the loading capacity increased from 55.3 to 70.2 kNm (26.94%). The results indicate that UHPSFRC-filled square steel tubular columns improve seismic performance by decreasing the axial compression ratio and by increasing the width-to-thickness ratio. When the width-to-thickness ratio was reduced, the steel tubular was able to provide higher lateral restraint to the internal UHPC; thus, seismic performance was improved. With the increase in the axial compression ratio, the second-order damage effect of the members was greatly affected, and it accelerated the plastic damage. A modified UHPSFRC model considering steel tubular constraints was adopted, and the nonlinear dynamic modeling of the column response using OpenSees led to good agreement with the tested response of the column under cyclic motion. The theoretical calculation model can better predict the bending capacity of the UHPSFRC-filled square steel tubular columns. However, the calculation formulas of initial stiffness and yield bending moment need further research. Full article

A concrete-filled steel tube (CFST) column permits convenient and fast construction, and its use for high-rise buildings is increasing. Meanwhile, the CFST structure has great potential for use in residence buildings, owing to its smooth evaluation. A connection for a flat CFST column has also attracted increasing attention from scholars. An innovative connection between a flat CFST column and an H beam was proposed and cyclically tested in this paper. The flat CFST column, with a width that is equal to the thickness of the partition wall, was adopted to avoid the protrusion of the column into the corner of the room. The configuration of the innovative connection was introduced, and three full-scale specimens, considering different relative positions of the beam and column, were tested under cyclic load to failure. The seismic performance, including the failure mode, ductility, etc., were revealed and evaluated. It was indicated that the plastic hinge of the connection was prominently removed outward, due to the reinforced short beam and the interior-diaphragm, verifying the reliability of the innovative connection. Furthermore, an elaborated finite element model was developed, and the results of the finite element simulation were compared with the experimental simulations. This comparison confirmed the reasonability of the developed finite element model. Full article

In recent years, cold-formed steel has been widely used in prefabricated steel structures, and the common cross-section forms are mainly complex lipped angle sections. However, there is a lack of design guidance for such a cross-section due to the complex geometric property. The restraint between adjacent plates cannot be considered proper for the traditional analytical method. Therefore, it is particularly important to study the stability bearing capacity of angle sections with complex edges under axial compression. In this paper, the finite strip software (CUFSM5) was used to analyze the critical stress of 1296 different angle sections under axial compression. The deformation diagram and the critical stress of elastic buckling were obtained. Considering the restraint between adjacent plates, the formula for predicting the critical stress of elastic local buckling of complex lipped angle sections was proposed and verified. Further, the critical stress of elastic distortional buckling of 918 complex lipped angle sections was analyzed by CUFSM. It was found that the cross-sections can be divided into two categories: cross-section without distortional point and cross-section with distortional point. It was found that the critical stress of elastic local buckling of the angle steel section can be significantly improved by the complex edge. Additionally, the critical stress of elastic local buckling of the section is less affected by the edge size for the complex edge section. The accuracy of the Hancock method for calculating the critical stress of elastic distortional buckling of complex lipped angle sections with distortional points was verified. The presented research can provide useful guidelines for designing cold-formed steel angle columns. Full article

Modular steel construction (MSC) consists of the off-site prefabrication of a fully finished module and the on-site assembling of the module unit. The popularity of MSC is on the rise, attributable to its technical advantages of speed and quality of buildings with repetitive units. Inter-module connection is critical for the overall stability and load-bearing capacity of MSC. An innovative, fully prefabricated liftable connection (FPLC) using standard corner fittings and long stay bolts is proposed in this paper. This paper focuses on the axial compressive behavior and design of FPLC. Five full-scale specimens were tested under axial compression. Local buckling of the column and shear of the long stay bolts were observed during the test. It can be concluded from the test results that the load-bearing capacity may decrease as the number and diameter of the stay bolts increase. A three-dimensional nonlinear finite element model (FEM) was developed and validated against the test results by general purpose finite element software ABAQUS. Furthermore, a parametric study was conducted using the verified FEM to provide a better understanding of the axial compressive behavior of the FPLC. The results of the parametric study indicated that the corner fitting can be up to 15% lighter for columns with thicknesses of 6 mm and 8 mm without substantial reduction of the axial load-bearing capacity of the FPLC. Moreover, the location of the column can be adjusted to achieve a uniform Von Mises stress and equivalent plastic strain (PEEQ) distribution of the connection. The presented research work provides an engineering-practical inter-module connection on its axial compressive behavior, which will provide helpful references for further application of MSC.
