摘要:
通过一个细观模型,从细观层次上分析了砌体在单调受压荷载作用下的损伤破坏机制,解释砌体受压应力-应变关系的非线性和应变软化,根据能量原理,建立了砌体轴心受压时的损伤本构关系模型,提出一类损伤函数表达式,利用应力-应变曲线特征条件和标准试件强度值确定模型参数,分析得出应力-应变关系仅与砌体的峰值点割线弹性模量与原点切线弹性模量有关,该式能反映砌体受压试验所表现的特征,与已有受压结果相比较,结果吻合良好.
Abstract:
Through a meso-model, the damage failure mechanism of masonry under monotonic compressive load is analyzed from the meso-level level, the nonlinearity and strain softening of the compressive stress-strain relationship of masonry are explained, and the damage constitutive relationship model when the masonry axis is compressed is established according to the energy principle, a class of damage function expressions is proposed, the stress-strain curve characteristic conditions and the strength value of the standard specimen are used to determine the model parameters, and the stress-strain relationship is only related to the elastic modulus of the peak point secant line of the masonry and the elastic modulus of the origin tangent. This formula can reflect the characteristics of masonry compression test, and the results are in good agreement with the existing compression results.
