Strength and performance of steel fibre-reinforced concrete stiffened plates

This paper presents the results of an experimental investigation conducted on full-scale specimens to examine the effect of using steel fibre-reinforced concrete (SFRC) on the strength and performance of rectangular stiffened plates. A comparison of the flexural response of identically designed SFRC and reinforced concrete (RC) stiffened plates is also presented. Both the SFRC and RC plates carried the design load with an adequate load factor. The midspan deflection was found to be well within the limits prescribed by design guidelines. An improved theoretical formulation to predict the ultimate flexural strength and/or the design of rectangular SFRC stiffened plates is also proposed.
