Nonlinear Static Analysis (Push-over) On SRC-RC Vertical Hybrid Structure

The steel reinforced concrete-reinforced concrete (SRC-RC) vertical hybrid structure has the advantages of SRC structure, and because of its good properties, the SRC-RC structure has been widely used in the modern high-rising buildings. Compared with Traditional structure forms such as SRC structure and steel structure, the SRC structure can effectively reduce the cost of construction, and has good seismic behavior. Based on the Push-over analysis method, this paper studies several SRC-RC vertical hybrid structures with different transfer story. And their seismic behaviors are studied.In this paper, The Basic Principle, the analysis procedure and the basic function of Push-over analysis method are introduced. By Using sap 2000 structure design program, a group of 12-story SRC-RC frame structural models and a group of 8-story SRC-RC frame structural models are established. Based on the results of Push-over analysis, the influences of transfer story change of SRC-RC vertical hybrid structure are studied.This paper compares the seismic behaviors of the structural models, and the preliminary study of the influences with the transfer story change on SRC-RC structures are discussed. All these may contribute to the further research of seismic behavior of SRC-RC structures.
