Paper Abstract

Complex frame structure is a kind of irregular structures formed through the vertical connection of original concrete frame structure and the new steel frame structure. This structure may have weak layer, and the deformation of weak layer usually influences the seismic capacity. Therefore, capacity spectrum method can not be used for evaluating this structure. Based on the characteristics of complex structure and the consideration of dynamical characteristic of each stage (including elastic stage; yield stage; initial failure stage and final failure stage) under the earthquake, this paper presents inter-storey capacity spectrum method which regards each storey as a separate evaluation subject. Finally the procedure of this method is given in detail with several examples which shows that inter-storey capacity spectrum method can be used for not only distinguishing the weak layer effectively but also identifying stress state of each floor under earthquake.
