Experimental and finite element analysis on the steel fiber-reinforced concrete (SFRC) beams ultimate behavior

A simplified finite element model for analysis of the Layered steel fiber beams with the concrete damaged plasticity model has been presented. The numerical simulation of load-deflection curve of layered steel fiber reinforced concrete beam under three-point loads is performed using ABAQUS. The results of simulation are generally in conformance with the experiment. The results of numerical simulation show that layered steel fiber has little contribution to the elastic capacity of concrete beam. But it can improve the ultimate bearing capacity of concrete beam obviously. The bending collapse style of layered steel fiber reinforced concrete beam is different from plain concrete beam evidently with obvious ductile characteristic.

The numerical simulation by nonfinear finite element method(FEM) was adopted to analyze the behavior and the influences of the fraction of steel fiber by volume fraction and the strength of steel fiber reinforced concrete on the bearing capacity and the ductility of reinforced concrete shearwalls. The results show that with the increase of the fraction of steel fiber by volume fraction, the bearing capacity and ductility coefficient of steel fiber reinforced concrete shearwalls increase gradually. With the increase of the strength of steel fiber reinforced concrete, the bearing capacity and ductility coefficient of steel fiber reinforced concrete shearwalls decrease. It proves the rationality of the unit type, stress-strain relation of material and failure criteria used in the finite element analysis model.

Carbon Fiber Reinforced

Carbon fiber-reinforced polymer (CFRP) sheets have recently become popular for use as repair or rehabilitation material for deteriorated carbon fiber reinforced concrete structures. Carbon fiber reinforced concrete beams were analyzed by finite element software ANASYS. Through the finite element analysis, the results showed that using bonded CFRP to strengthen R. C. beams can significantly increase their load carrying capacity. However, the beams with prestressed CFRP can withstand larger ultimate loads than beams with bonded CFRP. Using bonded CFRP to strengthen R. C. beams can obviously reduce the ultimate deflection.
