DOI: 10.25103/jestr.162.11
Abstract: During steel pipe jacking (SPJ), if improper control of jacking force or excessive water and earth pressure occurs, axial overall buckling and local buckling may happen. To reveal the stability mechanism of SPJ in the… read more here.

DOI: 10.3390/ma15196938
Abstract: This study investigated short thin-walled channel columns made of carbon/epoxy laminate. Columns with two multi-ply composite layups [0/45/−45/90]s and [90/−45/45/0]s were tested, with each layup having eight plies symmetric to the midplane. The columns were… read more here.
