密肋复合墙体结构轻质填充材料本构模型的研究
Stady on the constitutive model of the lightweight infilled material in multi-ribbed wall structure
【摘要】 通过对密肋复合墙体结构常用的轻质填充材料在含水率为(6±2)%时的单轴受压试验,确定了密肋复合墙体结构的轻质填充材料单轴受压本构模型,进而基于统一强度理论,结合抗拉强度及抗剪强度试验,确定了密肋复合墙体结构填充材料的多轴破坏准则,并建立了密肋复合墙体填充材料的弹塑性本构模型。
【Abstract】 Through the test of lightweight infilled material in multi-ribbed wall structure,a axial compression constitutive model of lightweight infilled material at the(6±2)% water content is proposed.Combined with the test of tensile strength and shear resistance,the failure criteria of lightweight infilled material in multi-ribbed wall structure is determined based on the unified strength theory,and an elastic-plastic constitutive model of lightweight infilled material in multi-ribbed wall structure is presented.
