Abstract: An experimental study of the ultralow-cycle fatigue of iron-based shape memory alloy (Fe-SMA) in triaxial stress states was conducted. Monotonic tensile tests of specimens with different geometries were carried out to ...

Abstract: Shear keys as sacrificial components are widely used in cap beams and abutments of highway bridges to limit the transverse displacement of superstructures and avoid damage of substructures. To investigate the seismic ...

Abstract: Rocking piers can limit the seismic damage and residual displacement under strong earthquakes to maintain the post-earthquake serviceability of bridges. This article presents an experimental study on the seismic response ...

Abstract: This paper shows that the mechanical behavior of concrete materials can be described by a nonlinear unified strength criterion which requires four independent parameters for model calibration. The criterion covers all the ...

Abstract: This paper presents results of a first-ever experimental study on the axial compressive behavior of large-scale square reinforced concrete (RC) columns confined with polyethylene naphthalate (PEN)/terephthalate (PET) ...
