Abstract
Dept of Civil and Architectural Engineering, Sungkyunkwan University, Suwon 440-746, KoreaABSTRACT Structures are often subject to vehicle collision which can be accidental or terrorist attack. Previous research shows that the damage in major columns may result in progressive collapse of a whole building. This study investigates the performanc e of a steel column standing on a reinforced concrete footing subjected to a vehicle collision. The size and the axial load of the steel column are determined based on the assumption that it is the first story corner column in a typical three-story building with s ix meter span length. The finite element model of a eight-ton single unit truck provided by the NCAC (National Crash Analysis Center) is used in the numerical analysis. The finite el ement analysis is performed using the LS - DYNA, and the results show that the beha vior of the column subjected to car impact depends largely on the column-foundation connection detail.Keywords : vehicle collision, progressive collapse, FEM explicit analysis
