2008 Wenchuan earthquake and Yushu earthquake in 2010 caused extensive damage to the brickwork structure. For the present form of this structure in China's vast rural areas and cities, there are a lot, and plays a very important role in our daily life, such as schools, hospitals, office buildings. Therefore, this type of structure to carry out earthquake damage prediction work has important significance to safeguard the sustainable socio-economic development, to reduce casualties and economic losses. The main work of this paper are as follows: 1. Introduction and summary of the main features of the brick structure and brick masonry structure in the previous earthquake structural damage. 2. Detailed earthquake damage prediction of brick masonry structures are two ways in which literature [1] with an average discounted shear strength as the main symbol of the seismic capacity of brick masonry structure obtained anti-seismic damage level and the average discounted The shear strength of the relationship, through statistical analysis, the they are inversely proportional relationship; literature [2] method is based on \Through practical examples, respectively, to verify the applicability of these two methods, showed that the method of the literature [2] more realistic earthquake damage, but more input parameters, the application of the more cumbersome; literature [1] advantage of input parameters relatively simple, convenient application, but in some cases, come to the earthquake damage is significantly larger than the actual earthquake damage emphasis enough precision, so it is necessary to correct [1]. Selected different regions, different layers, different age 200 brick structure, using the method of the literature [2] draw 200 brickwork \calculate their average discounted shear strength obtained earthquake damage level and the average discounted shear strength, then the method of least squares fitting, given 1-2 layers, 3-4 layers, 5-6 Finally, through the practical example of verification, the revised literature [1] method of calculation accuracy has been improved more in line with the actual earthquake damage.
