Performance-Based Design of SHCC Components – Research and Challenges

摘要: SHCC is a new class of materials with high tensile ductility and excellent crack control. Conventionally, mix design has been based on the direct behavior. In particular, compositions higher are considered to be better. However, recent experimental results have shown that stress-strain curve itself does not provide sufficient information for assessing structural durability performance components. some cases, an apparently poorer behavior can give rise better member performance. A performance-based approach which directly relate requirements component continuum properties or micro-parameters therefore required. This paper will discuss ongoing work related development this framework, highlight various challenges overcome.
