FINITE ELEMENT ANALYSIS ON THE STEEL FIBER-REINFORCED CONCRETE BEAMS: A SYSTEMATIC REVIEW
Main article
Abstract
Steel fiber-reinforced concrete beams have been widely researched, including static mechanical performances, fatigue behaviors, prediction of capability and so on. It is widely accepted that numerical simulations are useful as they reduce more time, materials of casting and testing processes. This paper reviews the effect of finite element analysis on the steel fiber-reinforced concrete beams with commercial software ABAQUS and combines the results of the literature including FEA investigations. More than 150 papers were downloaded and only 8 papers from all the downloaded papers included contents of simulation specimen procedures with ABAQUS. Those papers were seriously compared between each other about what constitutive relations selected and details of defining other parameters in this presented work. What kind of material models in ABAQUS software was used more often and how to define the important parameters in recent study was discussed. Furthermore, this paper discusses of the two most important factors which are simulation accuracy and calculation efficiency about FEA and analyses the influence parameters based on the results of literatures. In brief, FEA simulation of SFRC beams with ABAQUS could be accomplished in good agreement between the experimental and numerical predict results and the discrepancies in general could be less than 10% with suitable data of other researcher’s experiment, while the number will be limited to 5% with exact average data of experimental results based on the same group of material. It should be noted that ABAQUS software is valuable and enough accuracy for simulation of SFRC beams and already be general employed in project investigations in recent years based on literatures regarding SFRC beams.
