Abstract:
An experimental investigation was carried out on a total of 28 simply supported ferrocement I-beams loaded in flexure under two symmetrical point loads. The major parameters considered in the study were the shear span-to-depth ratio, compressive strength of the mortar, and amount of longitudinal and transverse reinforcement. The results of these are presented and discussed. Test results indicate that the beams fail in shear only when the span-depth ratio is less than or equal to 1.5. Beyond this value, failure occurs in flexure. Analyses are presented to predict the cracking and ultimate strengths of such beams in shear as well as flexure. A comparison of theoretical predictions with experimental results shows good agreement.
