摘要

超强韧性混凝土(PP ECC)具有较强的拉伸应变硬化特性,可将其与钢筋结合应用于结构构件中。根据材料试验结果,通过数据模拟,得到具有代表性的超强韧性混凝土材料受拉应力-应变模型,基于此对配筋超强韧性混凝土偏心受拉构件进行力学分析,通过数值计算,推导出各个受力阶段所对应的承载力公式。
        Propene Polymer Engineered Cementitious Composites( PP ECC) has stronger tensile strain hardening characteristics,which can be applied in the structural member by combining with reinforcing steel bar.According to the test results of materials,the tensile stress-strain model for the typical material of PP ECC is obtained from the data simulation,and the mechanical analysis on the PP ECC eccentric tension member of this reinforcing steel bar is made based on this. The corresponding formula of bearing capacity at each loading stage is derived through the numerical calculation.
