corresponding to the fundamental period of the structure defined as the intensity measure (IM).Because of uncertainty in calculating seismic demand and capacity, there would be some uncertainties in the results. This uncertainties can be measured by two uncertaintymeasures, uncertainty index and total uncertainty. In this research, four steel frames with 4, 8, 12 and 16 stories that are representative of structures with low to medium periods have been studied and the uncertainty index and total uncertainty have been calculated for each of them, using a number of records which were scaled in different levels of earthquake intensity. According to the obtained results, the uncertainty measures compared to each other.
