Flexural behavior of steel fiber reinforced concrete : experimental characterization and concepts for the design use

Abstract

Neste trabalho descreve-se a proposta da RILEM para caracterizar experimentalmente o comportamento em flexão do betão reforçado com fibras de aço. Com base na resposta força-flecha obtida nos ensaios experimentais são propostos conceitos de tensão equivalente e tensão residual para representar a resistência do BRFA fendilhado.This work describes the recommendations proposed by RILEM to assess, by experimental approach, the bending behavior of the steel fiber reinforced concrete. Based on the force-deflection relationship recorded from experiments, concepts of equivalent and residual flexural stress are proposed to represent the resistance of cracked SFRC
