This paper describes an experimental program to assess the cracking characteristic of High Performance Fiber Reinforced Cementitious Composite (HPFRCC) after damage. Four-point bending tests were conducted on pre-damaged HPFRCC plates having different initial damage levels and orientations. The result showed three unique cracking characteristics: a bi-directional crack pattern, the discontinuity of the secondary cracks, and a relatively orthogonal cracking pattern. Moreover, the initial damage was found to have a significant influence on the macroscopic response of the plate. |
