キーワード：microplane model, Multiple cracking, SHCC, マイクロプレーンモデル, 複数ひび割れ
The tensile properties of strain hardening cementitious composites are modelled by using multi-layer microplane model with multi-layered microplane structure. In the simulation to verify the validity of the present model, the statistical variation of material properties due to spatial distribution of short randomly distributed fibers is considered. The total crack widths and stress-strain relationship are examined for uniaxial direct tensile loading along with crack distribution and spacing and number of cracks. The analytical results are compared with experimental data. The uniaxial compression behavior is also verified. A good agreement is found in analytical and experimental values.
