NONLINEAR BUCKLING OF THE OPEN THIN-WALLED CURVED BEAMS

  • The stability of thin-walled structures is an importantproblem in civil engineering. In this paper, the nonlinear elastic bucklingof the open thin-walled curved-beam is analyzed by using the finiteelement method. Through the nonlinear regression computation for a greatnumber ofFinite-Element results, a practical and simple formula is obtained, whichcan be used to estimate the ultimate bearing capacity of the openthin-walled curved beams.
