钢筋混凝土筒仓开裂后的计算数学模型

CALCULATION MATH.MODEL OF CRACK PHASE OF REINFORCED CONCRETE CYLINDER SILO

在ＶＯＩＧＴ－ＲＥＵＳＳ模型的基础上，建立钢筋混凝土粮食筒仓壁开裂状态下的应力应变关系。分析中考虑到裂缝区混凝土的拉伸软化和骨料咬合作用，钢筋暗销作用，以及非裂缝区混凝土与钢筋之间的局部粘结滑移等因素。

Based on the VOIGT REUSS model,stress changes of crack phase of reinforced concrete cylinder silo was analysed in the paper.Meshing action between concrete and bone material in cracking area,and connection action between concrete and reinforced steel in non cracking area et al.were also considered.Finally,calculation math.model near practical stress phase on silo walls was established by the authors.
