Abstract:

© 2020, Springer Nature Singapore Pte Ltd. Hybrid fiber reinforced polymer (FRP)-concrete-steel double-skin tubular column (DSTC) is a new form of composite column that consists of an outer FRP tube and an inner steel tube, with inner space filled with concrete. This study presents the first numerical investigation on the behavior of hybrid DSTC under lateral impact loading using LS-DYNA. The numerical models of hybrid DSTC were first developed and then verified by using existing test results. Afterwards, parametric analyses were conducted to investigate the influences of impactor shape and impact energy on the lateral impact behavior of hybrid DSTC. The impact force-time history and mid-span deflection-time history of hybrid DSTC were extracted from the simulation results. The simulation results show that hybrid DSTC behave in a very ductile manner under lateral impact loading. The impact energy can significantly influence the impact behavior of hybrid DSTC. However, the influence of impactor shape is insignificant.
