This literature review paper presents the latest technologies, designs and technics which has been used to improve the transverse impact resistivity of Concrete Filled Steel Tubes (CFST). Moreover, this literature review paper has included past researchers in the field since 1976 up to 2020. Different types of concrete filled steel tube designs and materials subjected to lateral/transverse impact load were discussed, for example, (1) Concrete Filled single skin Steel Tubular - CFST, (2) Concrete Filled Double skin Steel Tubular - CFDST, (3) Concrete Filled Stainless Steel Tubular - CFSST, (4) High Strength Concrete-Filled Steel Tubular - HSCFST, (5) Concrete Filled Steel Tubular - CFST structural elements strengthened with Fiber Reinforced Polymer - FRP, (6) Reinforced Steel Concrete Filled Steel Tubular - RSCFST, (7) Partially Concrete-Filled Steel Tubular - PCFST structural elements. Besides, the methodologies used by past researchers were argued in terms of geometrical properties, type of analysis, material properties, cross sectional dimensions and boundary conditions of CFST’s. In addition, the numerical mesh, elements, loading conditions used by previous studies were illustrated. Furthermore, the results of previous researchers were examined in terms of failure modes, Impact Force versus Impact Time and Mid-span Deflection versus Impact Time and residual displacements. The core of the problem is the high deflection magnitudes in CFST structural members after being exposed to transverse impact loads. As such, this literature review paper proposes an innovative hybrid design using composite materials to improve the resistivity of concrete filled steel tubes after being exposed to transverse impact load.
