Abstract:
While the benefits of fiber-reinforced concrete (FRC) have been widely investigated, much of the literature focuses on steel FRC subjected to monotonic loads. Data on the structural behavior of macro-synthetic polypropylene FRC or FRC under cyclic loads are scarce. A pilot investigation on the shear behavior of polypropylene
FRC and on the behavior of FRC under reversed cyclic in-plane shear loading was undertaken. Five in-plane shear panel tests were performed. The parameters under study were the fiber material type (steel or polypropylene) and loading protocol. Additionally,
a number of compression, direct tension, and flexural tests were
performed to determine the material properties of the concretes for
comparison. Results show that the material response of 2.0% by volume of polypropylene FRC is nominally similar to that of 1.0% steel FRC.
