Study on Seismic Behavior of Steel & Concrete Hybrid Structure
Seismic behavior of the steel & concrete hybrid structure is studied by Sap2000, including modal analysis, response spectrum analysis and time-history analysis. Also, a simplified calculation model of the steel & concrete hybrid structure is established, and some formulae have been derived from this model, such as the natural frequency, top displacement, shear of both the core tube and the steel frame, on the basis of finite element method of bar system. Those formulae can be used to explain and approximately count the seismic response of steel & concrete hybrid structure.
