finally, the new system model is validated by a set of uniaxial tension test data of concrete, which had been performed by authors in the laboratory.
最后,通过在实验室完成的一组混凝土单轴拉伸试验验证了这个系统模型的合理性。
the method of uniaxial tension test of concrete under ultra-low loading rate is described. it can be used to determine the characteristic curve of concrete under loading condition.
本文介绍极慢速加荷条件下混凝土轴向拉伸试验方法,它能测定混凝土受载时的特性曲线。
in this research x65 pipeline steel is chosen as the test material, and uniaxial tension test and cod test of x65 are made.
本研究采用x65管线钢为实验材料,对其进行了单轴拉伸实验和三点弯曲实验;
