Localization of the bending response in presence of axial load

n this paper, we study the e€ect of a small misplacement on the de¯ection response of the two-span column that is subjected to transverse loading. Whereas the buckling modes of such and other structures have been investigated thoroughly in the literature, the authors tend not to investigate the most important quantity, namely, the columnʹs response. This gap is attempted to be ®lled by the present study. It is remarkable that a 3% misplacement may lead to a ®ve-fold enhancement of the response, and thus, location imperfections cannot be overlooked for safe design. 7
