自保温组合砌体是一种集保温和承重于一体的新型结构,为了研究其竖向承载力及其破坏特征,通过三片模型墙体竖向承载力试验和实测材料参数的有限元分析,获得了组合墙体承载能力、位移等相关基本力学性能和破坏特征。对试验结果和有限元分析结果就进行比较,有限元承载能力低于试验值10%左右,竖向变形、破坏裂缝形式基本相同。采用实测材料参数建立的有限元模型可以用作自保温组合砌体结构的承载力分析,具有一定的工程意义。
In order to study its vertical bearing capacity and its failure characteristics, the self-insulation combined masonry is a kind of new structure integrating thermal insulation and load-bearing. Through the vertical bearing capacity test and the finite element analysis of measured material parameters, The basic mechanics performance and failure characteristics of combined wall bearing capacity and displacement were obtained. The test results and the finite element analysis results are compared, the finite element carrying capacity is lower than the test value of about 10%, vertical deformation, destruction of the fracture form is basically the same. The finite element model established with measured material parameters can be used as bearing capacity analysis of self-insulation combined masonry structures, which has certain engineering significance.
