摘要：
The mechanical behavior and fracture mechanisms of SHCC member failed in diagonal shear were evaluated both experimentally and analytically. Ultra High Performance Strain Hardening Cementitious Composite (UHP-SHCC) was applied as structural material. In the analysis, shear transfer model for SHCC was proposed based on its characteristics of cracking, that is, multiple fine cracking during strain hardening region and localization in one crack during strain softening region. As results, it was confirmed that proposed model was suitable for the mechanisms of shear transfer of SHCC and reasonable to predict the behavior of SHCC beam failed in diagonal shear.
