“…In the last few decades, thin-walled steel structures have been widely applied in engineering structures owing to their favorable seismic performance in regions which are exposed to severe earthquakes [1][2][3][4][5]. Due to their high strength, light-weight, ductility, and torsional rigidity, thin-walled steel structures are used in numerous modern applications such as urban highway bridge systems where the constructional space is limited [2][3][4][6][7][8][9]. In the event of heavy earthquakes, thin-walled steel tubular cantilever bridge piers are vulnerable to local and overall interaction buckling damage [1][2][3][4]9].…”

The current work presents a unique study on the seismic performance of innovative corrugated-plate steel bridge piers. While several previous research was conducted on steel tubes with cross sections such as rounded or semi triangular plates, the seismic performance of such structural members with straight ribbed corrugation geometry under uniaxial cyclic loading remained a research gap. Thus, this research aims to present a new concept that could add a promising design to steel tubes under seismic effect. The seismic performance of such piers was numerically investigated in terms of the load-bearing capacity and local buckling. ABAQUS was employed to accomplish a series of finite element analyses on corrugated-plate steel bridge piers under constant axial dead load and lateral cyclic displacement. Three different geometries of corrugated-shaped steel tubes (i.e., C60, C80, and C146 mm deep) along with four different thicknesses (i.e., 6, 8, 10, and 12 mm) were investigated and compared to the traditional circular-shaped steel tubes (i.e., Cir) having same thicknesses and outer diameter. The results revealed that the innovative corrugated-plate steel bridge piers offered 20% greater load-bearing capacity and 66% more ductility compared to their companions of circular-shaped steel tubes. It was interesting to notice that the peak value of the load-bearing capacity of the C146 column was greater than those of the C80 and C60 columns by 7% and 10%, respectively. Furthermore, the local buckling was generally seen less severe amongst corrugated-plate steel bridge piers. This research raises the importance of corrugated-plate sections used in bridge piers over circular shapes owing to their advantages in strength and aestheticism.

To rapidly restore the seismic behaviour of a portal steel bridge column after an earthquake, the installation of replaceable tubular steel piers at the root of a portal steel bridge column is proposed herein. In this study, various tubular steel piers with different structural measures were designed; an axial compression test and a numerical simulation of the newly designed tubular steel piers were performed. The effects of parameters such as the structure of stiffening rib, the strength of LYP steel plate, the size of low-yield-point (LYP) steel plate, and the size of outer constrained steel plate were discussed. The results indicate that local buckling of steel tubular plates is likely to occur at the upper or lower end of those specimens, which belong to type II-A specimens with stiffened LYP steel tubular plates or type III-A specimens with T-shaped LYP steel plates, respectively. This led to the LYP steel plate cannot fully display its function. For type III-B and III-C specimens with embedded LYP steel plates and constrained steel plates on both sides, when the outer steel tubular plates buckle, the internally constrained LYP steel plates provide support for the outer steel tubular plates. The plastic deformation of the specimens is sufficient, and the deformation performance is good. For type IV-A specimens with LYP steel tubular plates and constrained steel plates on both sides, the mechanical behaviour of the new tubular steel piers is significantly improved, and increasing the height of the constrained LYP steel tubular plate can improve the compressive behaviour of the new tubular steel pier. Considering the effect of the steel plate thickness on bearing capacity and deformation performance, the thickness tw of the outer constrained steel plate should be equal to the thickness t of the common steel tubular plate, and the thickness tf of the LYP steel tubular plate should satisfy t ≤ tf ≤ 2t. Finally, a design formula is proposed to calculate the axial bearing capacity of newly designed tubular steel piers with constrained LYP steel plates.
