Abstract:
Torsion tests of six reinforced fibrous concrete beams with supplementary tests on fibrous concrete in direct tension and pullout tests on individual fiber are reported. The major parameters of the study were the volume fraction of fibers and percentage of bar reinforcement. The cracking behavior of beams and their complete torsional response were investigated. The softened truss model for conventional reinforced concrete beams has been modified, and torque-twist and torque-strain (both steel and concrete) curves were derived and compared with test results. In general, a good agreement is obtained.
