| 摘 要： | 结合已有结论和具体试验结果,研究了塑性混凝土弹性模量的试验方法,对计算公式中割线点的选定进行探讨,认为塑性混凝土受压应力一应变曲线的应力上升段中,从0．3倍峰值应力到0．7倍峰值应力为斜率较为稳定阶段,并据此建议了塑性混凝土弹性模量计算公式中割线点的取值．

| Abstract: | Base lastic modulus from O. 3 times presslve culating strain points d on recent testing results and previous existing conclusions about calculating method for the e- of plastic concrete, of which the test method is studied. Research results indicate that the slope peak stress to 0.7 times peak stress remains slightly stable in the upward section of axial com- stress curve of plastic concrete. Therefore,it can be recommended that the elastic modulus cal- should better be 0.3 times peak stress and 0.7 times peak stress. |
