该文在六片1/2比例节能砌块隐形密框墙体低周反复加载拟静力试验基础上,并结合节能砌块隐形密框墙体的特殊构造,建立了弹性阶段墙体的复合材料等效弹性板力学简化模型,其中包括两种正交各向异性复合材料计算模型,进而将墙体简化为各向同性的计算模型,给出了墙体弹性模量及剪切模量实用计算公式,为节能砌块隐形密框墙体的实用弹性刚度计算公式提供了必要的参数。将理论计算与试验结果进行对比分析,对墙体的弹性抗侧刚度的计算公式进行修正,提出了适合于节能砌块隐形密框墙体的弹性抗侧刚度的计算公式。结果表明:复合材料力学简化模型具有一定的理论依据和实用价值,能够满足实际工程计算需要。
Based on the low-cycle repeated-loading pseudo-static test of 6 1/2 energy-saving block masonry-sealed frame walls, combined with the special structure of the energy-saving masonry invisible frame wall, The material equivalent elastic plate mechanics simplified model, including two orthogonal anisotropic composite calculation model, and then simplified the wall isotropic model, gives the wall elastic modulus and shear modulus practical The calculation formula provides the necessary parameters for the calculation formula of the practical elastic stiffness of energy-saving block stealth dense wall. The theoretical calculation and test results are compared and analyzed, the calculation formula of the elastic lateral rigidity of the wall is modified, and the formula of elastic lateral rigidity of the wall is proposed. The results show that the simplified model of mechanical mechanics has certain theoretical basis and practical value, which can meet the needs of actual engineering calculation.
