Title: Study on nonlinear finite element analysis of steel fiber concrete structure
Abstract: According to the characteristics of steel fiber reinforced concrete structure,its non-linear finite element method were studied.Analysis focused on solving the constitutive relation of the materials and the effect of steel fiber to determine the finite element simulation.The influence of steel fiber on the structure can be taken into account by modifying the constitutive relation of concrete,regarding steel fiber as unit equivalent steel or overall equivalent steel,Unit equivalent steel method can simulate the bond-slip effect between steel fiber and concrete,however,large computation and the convergence process is not easy.In addition,the finite element analysis and existing experimental results were compared,the results show that the use of this finite element analysis to determine the concrete and steel from the stress distribution,fracture distribution and load-deflection curves with the test results close to,which can provide some reference for the performance analysis of steel fiber reinforced concrete structure.
