摘要:
对粉煤灰砖砌体试件进行了受压全曲线试验研究,研究了其强度、破坏形态、应力-应变曲线等特征,考虑了不同砂浆强度的影响,并与普通砖砌体试验的结果进行了对比,结果表明,粉煤灰砖砌体的轴压性能与普通砖砌体类似,采用普通试验机并辅以刚性元件,能测得受压应力-应变全曲线,基于细观损伤建立的本构关系则能较好地预测其应力响应.
Abstract:
An experimental study of the axial compression constitutive behavior of brick masonry with fly ashhas been performed using, prism specimens subjected to axial compression, Loading through a testing machineunder the force control with added stifiness elements is used to get the complete stress-strain curve, The maintest results including failure modes, strength and curves of stress-strain are given and discussed. Its compres.sion constitutive behavior is similar to that of brick masonry, It is found that the predictive results of stress-strain agree well with experiments based on existing meso-damage constitutive relation.
