Meanwhile, the buildings were also assessed by seismic actions, nature of using, capacity of seismic resistance, seismic site、 foundation and damage of adjacent buildings and so on. The advantage of this method is that the buildings on seismic site can be assessed in short time and the assessment results are accurate and reliable, if there have enough experts. The disadvantage is that the number of experts in our country too little to meet the demand on seismic site. Meanwhile, the experts can not be transported. Based on above reasons, a kind of method is needed, which not only uses expert knowledge and experience, but also meets timeliness, and avoids affecting assessment efficiency because of limit expert number. In the paper, safety assessment of building method is advanced, which is in the base of math model. Firstly, the aim and meaning of safety assessment is explained, in the same time, theory basis of numerical calculation method is introduced. Otherwise, through summarizing and concluding of prior a large of post-assessment experience, three kinds of functions is selected, which is geared for safety assessment. These functions use most computing examples to go in inversion analysis, so that, correctional parameter in the function and weighted value of each affected site. In the end, according to example calculation analysis of larges of buildings at many times earthquake, and comparing to real earthquake damage statues, the reliability of math model and calculation method is verified.
