Fatigue performance evaluation of plain and fiber-reinforced concrete using wedge splitting test

Paper in proceeding, 2009

The presented study focuses on the possibility of using wedge splitting test method to study the fatigue behavior of concrete. Moreover, the application of existing material models for fatigue performance of fiber reinforced concrete is further investigated. Fatigue behavior of three types of concrete, i.e. (1) plain concrete, (2) steel fiber-reinforced concrete, and (3) synthetic fiber-reinforced concrete, were studied experimentally and numerically. First, experiments were carried out using wedge splitting specimens subjected to monotonic and cyclic loading. Next, using inverse analyses and numerical analyses, bi-linear stress-crack opening relationships were estimated.
