Abstract:The stressstrain curve of common brick masonry in compression is completely
described based on compress test results of literature and constitutive relationship of concrete. At the same time,a mathematic model of 5 degrees polynomial is used,and the whole process of common brick masonry in compression is described by one smooth curve. The results of contrast indicate that the proposed model is feasible and meets the request of engineering calculation and finite element analysis.
