Abstract: It summarizes advances at Anti-Seismic Level. The problems are explored at level in different categories of importance building in code for seismic design of buildings and standard for classification of seismic protection of building constructions. Further consummate the necessity and feasibility for our country the class A,the class B and Ding Lei constructs seismic fortification goal and the standard are proposed. The differences in the class B construction when the seismic function cannot interrupt the life linear dependence construction which as well as with the personnel centralized construction or must restore as soon as possible in the seismic function has discussed and the safe seismic fortification principle embarked from both the economy to the class B construction has given the segmentation. The different important category construction earthquake resistance fortification goal and the standard has given using the probability analysis method.
Keywords: seismic design; fortification goal
