PROGRESS IN SEISMIC BEHAVIORS OF THE COMPOSITE STEEL-CONCRETE STRUCTURES

The seismic behaviors of composite steel-concrete structures are widely studied due to their extensive engineering applications in the major national construction projects and are reviewed in this paper, including the composite beams, the composite columns, the composite joints and the composite frames, as well as the characterization of the transfer of forces and the damage evolution. The modeling schemes, to simulate the seismic behaviors of steel-concrete composite frames are discussed, including the micro finite element modeling, the macro finite element modeling, and the multi-scale finite element modeling. The seismic performance evaluation of composite structure systems is also discussed.
