| Abstract: | The constitutive model of thermal insulation block by simulating stress in masonry of 1 ： 1 size of autoclaved aerated concrete block is obtained. We can simulate the compression character of blocks in masonry and constitutive equations by use of the frictional force between the loading boards with block. It can provide the basic mechanics parameter for finite element analysis by analyzing test data of stress and strain curve in five blocks. There are some dispersed for data of test. There are more differences between the max stresses with the strain as compared with common concreter. The constitutive equation curve obtained by analysis of test data is fit for the result of test. The mechanics character can be obtained by stress and strain curve of insulation blick. The constitutive equations based on test can be used to analyze the fi nite element in insulation masonry. |
