Abstract

This paper presents an experimental investigation into concrete filled steel tubular (CFST) members under lateral impact at mid span using a dropped weight moving with low velocity. A series of tests were carried out to obtain the residual deformation mode and the time histories of impact loads. The testing parameters include, impact energy and the axial level on CFST. Based on the testing data, stability value of impact force, time of duration impact, as well as the maximal deformation at mid span of the composite members under different axial load level and impact energy are analyzed and discussed. Keywords: concrete filled steel tube (CFST), hollow tube, concrete, lateral impact axial load level energy failure mode.
