Abstract: With software ETABS and SAT'WE, a reinforced concrete office building where one steel structure layer is added on its top is analyzed seismically using three kinds of computation modes. Compared the nigidity, period, displacement and inner force of original structure with the structure after adding one steel storey, we find it is necessary to analyze the whole structure due to the significance of the computation results. And the results show that the period increases and the total bottom shear force varies inconspicuously after adding one steel storey, which can guide the similar structural design significantly.
