The eccentric compression behavior of the CFSTs reinforced with inner latticed steel angles was experimentally investigated, and test results, such as the load–displacement curves, load‐strain curves, distributions of lateral deflection, and ultimate load, were obtained and analyzed. Test results showed the influence of the latticed steel angles on the ultimate load was not obvious when the steel consumption was relatively small, and the lateral deformation was not obvious when the compression load was smaller than 80% of the ultimate load. The corresponding finite element (FE) model was established and validated by the test results, and parametric analysis was also conducted subsequent to validation. The analysis results showed the contribution of latticed steel angles to the ultimate load would be diminished as the eccentric distance increases. Moreover, the design equations for the ultimate load were proposed based on the FE results, and the calculation results indicated the proposed design equations can predict the ultimate load conservatively and safely.

“…As can be seen (Figure 18), the Chaboche model inherently considers material behavior to be Masing. This model, and the others, 18,34 cannot be used for materials that show non‐Masing behavior, as the material parameters, in such a case, will vary with strain amplitude. Despite this fact, these models have been extensively used for the simulation of the LCF behavior of materials and structures 121,127 .…”

“…The combined nonlinear isotropic–kinematic hardening model has been used extensively for the simulation of the fatigue behavior of materials or components 17,33 . This model and a few others 34 are available in the commercial finite element analysis codes like ABAQUS and ANSYS, but none of these has the ability to simulate the non‐Masing behavior. An actual component or structure with a variable cross‐section experiences different levels of stress/strain at different locations under cyclic loading.…”

Over the last 50 years, many researchers have contributed significantly towards understanding the Masing/non-Masing behavior of materials. However, there has been no review article or scientific report published to date that highlights the progress made in this domain. This article presents a state-ofthe-art comprehensive review and analysis of the Masing/non-Masing behavior of materials under low cycle fatigue loading. Understanding of Masing/ non-Masing behavior is important for the development of fatigue-resistant materials, prediction of fatigue life, and constitutive modeling and simulation. The influence of various factors such as stacking fault energy, temperature, strain amplitude, and loading conditions on Masing/non-Masing behavior has been summarized in this article. The literature pertaining to the internal microstructural changes observed in different materials by various researchers has been collected and compiled. The different methods of analyzing Masing/ non-Masing behavior reported in the open literature are assessed and presented. The importance/significance of Masing/non-Masing behavior in constitutive modeling and fatigue life prediction has also been highlighted. Finally, conclusions based on the review and the potential problems required to be resolved in the future are also pointed out.

“…The true stress-strain curves obtained from the tensile coupon tests were used for the steel tubes. The constitutive model of steel was defined as von Mises yield criterion, associated with a flow rule with isotropic strain hardening [23,24]. The weld was assumed to have the same material properties as those of the steel.…”

Behavior of Corroded Thin-Walled Concrete-Filled Steel Tubular Stub Columns

The behavior of two series of corroded thin-walled concrete-filled steel tubes (CFSTs) was investigated in this paper. One series, called the CT series, consists of fourteen CFST specimens corroded by NaCl solution, while the other, called the AT series, consists of six test pieces corroded in the atmosphere. Outer surfaces of corroded steel tubes were scanned using a 3D scanner machine, and a complete surface profile of each specimen was obtained for corrosion evaluation using different methods in this study. Entire test pieces were compressed to failure, and their behaviors under loading were recorded. It is shown that corrosion has a fractal feature, and it has a significant effect on the ductility of specimens. In addition, FEA models of corroded CFST specimens were established based on the 3D scanning profile results using the ABAQUS program and verified against column test results.
