摘要:

通过对9块1/2比例密肋复合墙体模型的抗震性能试验,探讨了影响墙体弹性刚度的主要因素; 结合密肋复合墙体的特殊构造,建立了墙体的复合材料二相体力学模型; 按照混凝土与砌块体积比不变原则对肋梁、肋柱同时加强,得出墙体的弹性计算常数及剪切常数; 在此基础上,进一步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,为密肋复合墙体的实用弹性刚度计算公式提供了必要的参数,并且计算结果与试验值吻合较好,说明该模型具有一定的理论依据和实用价值,满足实际工程计算需要。

Abstract:

Through aseismic performance test of nine 1/2-scaled multi-rib slab composite wall model, authors discussed the main factors of influencing wall elastic rigidity. Considering the special structure of multi-rib slab wall, founding diphase body mechanical model of compound material, strengthening rib beam and rib pillar by equivalent volume ratio of concrete and slice brick, authors drew elastic computing constant and shear constant. Based on the things, authors simplified isotropy computation model to wall; gave practical design formula of elastic module and shear module; provided necessary parameter for practical design formula of elastic rigidity. The calculation results agree well with the text results, which mean that this model has certain theoretic basis and practical value, also, it can meet the demand of engineering calculation.
