Abstract: Abstract Compared with the excellent energy absorption performance under axial loading, thin-walled tubes are vulnerable to instable global bending under oblique loading condition. In this paper, a novel design was developed to improve the energy… read more here.

DOI: 10.1016/j.jcsr.2019.105899
Abstract: Abstract For circular steel sections, axial slenderness limits are typically defined in terms of the diameter-to-thickness ratio and indicate whether the member will first yield or locally buckle under axial compression. The common opinion is… read more here.

DOI: 10.1155/2020/4028907
Abstract: Finite element models (FE models) of high-strength steel Q420 (yield strength 420 MPa) circular tubes considering residual stresses and local and overall geometric imperfections were established and verified against existing test data. Based on parameter analysis,… read more here.
