| Research Abstract |
Severe loading conditions such as tension-compression fatigue and fatigue with the presence of water are encountered in some structural applications of HPFRCC (High Performance Fiber Reinforced Cement Composite). First, the material properties of HPFRCC under such conditions are clarified experimentally, and a micromechanics based model is developed. Next, procedures for structural analysis under those conditions are developed with the micromechanics model utilized. Stress and damage states of HPFRCC structures are analyzed, and finally the durability of those structures is evaluated.
