摘要：

The objective of the present investigation is to study the toughness of steel fiber-reinforced concrete (SFRC) based on the Japan Society of Civil Engineers (JSCE) approach. Two aspect ratios of fiber and two different concrete strengths are considered. The toughness factor as measured by the JSCE approach is reported and there is a good correlation between the fiber-reinforcing index and the calculated toughness factor. It is observed that this approach is quite simple and any suitable deflection measuring technique can be employed. Though this method raises some concerns, the advantages are significant.
