What is it about?
This paper demonstrates the numerical verification of the experimental outcomes and an extensive study on some factors that affect the CFRP-RC component's response. Additionally includes a general overview and basic theory of finite element formulation for dynamic members also how ABAQUS determines the deflection of the members. Due to the strain rate sensitivity of concrete and steel, this study detailed the equations incorporated in the material characteristics of the ABAQUS software module.

Why is it important?
The purpose of this research is to assess the performance of CFRP strengthened full-scale metro building station members subjected to hits by train head lateral impact. The present study aims to bridge the knowledge gap, build on these preliminary research investigations, generate new information on the effects of controlling parameters, and develop a comprehensive database of column behavior under unequal lateral transverse impact.
Perspectives
The key response parameters in this study are the peak impact force, impact duration, and maximum deflections. The input load parameters are the impact mass, initial impact velocity, impact location, impact contact area, and impact height. The input structural parameters are strain characteristics of steel bars, reinforcement ratio, impact velocity, CFRP-RC member's properties configurations (i.e., thickness, orientation, type), and ductility index.
