To check the problem of weak story is required by using the calculation of the ultimate story shear of each level in our seismic design code. But, this calculation is a complicated method in the design procedure. Especially if we check a high building, it needs a lot of time to manual computing. On the other way, the engineering can use the program of ETABS for analysis. The calculation can be replaced by the nonlinear pushover and the result of comparison will be discussed in this paper. The suggested method shows more fast and safe for checking a high building.
