“…19 The existing research results show that corrugated steel plate-concrete composite members have good mechanical properties and economy. [20][21][22][23][24][25] An innovative cross-section PEC column with corrugated webs (CPEC columns; see Figures 1 and 2) was proposed in this paper to improve the mechanical properties of traditional PEC columns, which can promote the use of PEC columns in high-rise buildings. Corrugated plates can improve the stiffness and bearing capacity of PEC columns, and at the same time, corrugated plate can also increase the adhesion between the concrete and web.…”

SummaryPartially encased composite (PEC) members are becoming increasingly popular because of their high strength and suitability for prefabrication and assembly. Corrugated steel plate has higher out‐of‐plane stiffness than flat steel plate. When it is combined with concrete, the bonding between corrugated steel plate and concrete is more obvious than that between flat steel plate and concrete. For this reason, a new type of corrugated web PEC column (CPEC column) was proposed in this paper, and its eccentric compression performance was studied by experiment and numerical method. Nine specimens were tested, of which two were subjected to axial compression and seven were subjected to eccentric compression. The key factors considered in the experiment were the loading direction, load eccentricity, link spacing, and width‐to‐thickness ratio of flange. A three‐dimensional finite element model of the CPEC columns was established and verified, and the influence of the wave angle of corrugated web on the behavior of CPEC columns under eccentric compression was investigated using a parametric study. Finally, the current design codes for estimating the interaction curve and bearing capacity of CPEC columns were assessed.

“…These studies have shown that the CFDST posts are significantly more resistant, stiffer and able to disperse strongly thanks to a strong hold between the tubes and the concrete. These advantages result in better cyclic behavior, higher fire resistance, and fast and economical construction (Fang et al 2021;Liu et al 2022), so CFDST columns are widely used in the field of engineering. With the same loadcarrying capacity, CFDST columns have lower weight, higher section modulus, bending stiffness, strength, ductility, energy dissipation, seismic behavior and fire resistance than concrete-filled tubular steel columns (Abedi et al 2008;Ghannam et al and Fawzia et al and Li et al 2020).…”

The concrete-filled double tubular steel column (CFDST) is a composite column that shows remarkable potential for the construction of tall buildings and bridge piers. When this type of column is exposed to external forces such as collisions with ships or cargo vehicles, explosions or fires, it loses strength. The outer steel tube of the column is affected, resulting in the loss of the concrete inclusion between the two layers of steel. As a consequence, a significant drop in column strength becomes evident. The aim of this study is to investigate the effects of cyclic loading on CFDST columns with a new reinforced circular cross-section, which have a constant number of stiffeners and stirrups over the entire column. Two specimens were subjected to constant axial compression and lateral cyclic loading to compare the behavior of a proposed reinforced cross-section (new reinforced cross-section) with that of a simple cross-section. The data from the test was used to validate a finite element analysis (FEA). Subsequently, the validated numerical models were used to evaluate the effects of various parameters, including the thickness of the pipes and the compressive strength of the concrete, on both cross-sections. In summary, the results show a significant improvement in the cyclic behavior of the column with a reinforced cross-section compared to a simple cross-section. The recommended reinforced cross-section thus prevents a sudden drop in column strength after the outer steel tube has been damaged.

“…Some engineering structures in long-term service, in addition to the need to withstand static loads, have to resist fatigue loads, seismic action, etc. The stress-strain relationship of concrete under cyclic loading determines the ductility and hysteresis performance of the structure under fatigue loading (Nehdi et al 2005;Fang et al 2021), and research on cyclic loading has been developed very rapidly in recent years. Deng and Sun (2001) studied the mechanical properties of steel fiber reinforced concrete (SFRC) and carbon fiber reinforced concrete (CFRC) under cyclic and established the respective constitutive equations.…”

In this paper, the mechanical properties of 84 different hybrid fiber recycled aggregate concrete under cyclic compression are designed and studied. The modification effect of four kinds of hybrid fiber combinations of steel fiber (SF) and carbon fiber (CF), glass fiber (GF), polyvinyl alcohol fiber (PVA) and polypropylene fiber (PF) on recycled aggregate concrete (RAC) is analyzed from macro and micro point of view. The fracture interfacial inclination angle model considering fiber content was proposed, and the strengthening mechanism of fibers under cyclic loading was discussed The results show that the addition of fiber changes the failure mode of recycled aggregate concrete, SF has a great influence on the main fracture inclination angle of the specimen, while the fracture mode of carbon fiber makes it have a good crack resistance effect, and the combination of SF/CF can significantly increase the peak stress of RAC. SF/PVA combination has remarkable toughening effect and plastic strain inhibition effect. The stress degradation process model of hybrid fiber recycled aggregate concrete was proposed. Finally, according to the experimental results, the uniaxial cyclic compressive stress-strain constitutive equation of hybrid fiber concrete considering the fiber characteristic index was established.
