Finite element analysis of bending performance of basalt fiber reinforced concrete beam

摘要

In this paper, through different reinforcement ratio and basalt fiber content, ultimate bearing capacity, stress-strain of regenerated concrete beam of basalt fiber were studied. As the result, basalt fiber reinforced the flexural performance of the recycled concrete beam obviously, the proper ratio of reinforcement can obviously enhance the flexural behavior of the basalt fiber recycled concrete beam too. Through simulation analysis, when the basalt fiber content is 2kg/m~3, the bending strength of basalt fiber regenerated concrete beam is the most obvious. The formula of yield bearing capacity about basalt fiber regenerated concrete beam fiber is simulated, the error between the calculated value and the simulated value is within 5%.
