Transverse Impact on Hollow and Concrete Filled Steel Tubular Members

Abstract

This paper clarifies a review of research progress in the transverse impact process on hollow and Concrete Filled Steel Tubular (CFST) members and their dynamic response under impact loading. This review emphases analytical, numerical and experimental studies recently performed by many researchers. It clarifies the influence of some fundamental parameters on the impact performance such as; axial load level, impact energy, steel ratio, constraining (confining factor), steel tube thickness, diameter-to-thickness ratio of the steel tube. In addition to exploring the effect of concrete and steel material properties and specimen boundary conditions. It also goes through the effect of using Carbon Fiber Reinforced Polymer (CFRP) jackets. The review explained with detailed discussions the stages of impact process, impact energy, dissipated energy, failure modes, life-cycle performance of Concrete Filled Steel Tubular (CFST) members subjected to impact load. The influence of strain rates on the performances of concrete and steel are discussed as well.
