通过对土坯砌体试件进行基本力学性能试验,就其抗压强度及应力-应变关系进行了研究和探讨,在试验研究与理论分析的基础上采用分式方程拟合了土坯砌体单轴受压应力-应变曲线,建立其单轴受压本构方程,给出了本构方程中参数的拟合值和明确的物理意义,研究成果可为土坯砌体房屋抗震性能分析提供参考。
Compressive strength and stress-strain curve were investigated and probed by test of basic mechanical properties of adobe masonry. Based on experimental study and theoretical analysis, the fraction equation are put forward to simulate uniaxial compression stress-strain curve of adobe masonry, the uniaxial compression constitutive equation is established, the fitted value and specific physical meaning of parameters in constitutive equation is analyse the seismic performance of adobe assigned. These works can also provide parameters in order to masonry houses.
