Study on Seismic Performance of Steel-Concrete Mixed Structure Compared with Concrete Structure
Seismic performance of the steel-concrete mixed structure is studied compared with concrete structure by Sap2000, including modal analysis, response spectrum analysis and time-history analysis. Also, a simplified calculation model of the steel-concrete mixed structure is established, and some formulae are derived from the model including the natural frequency, top displacement, shear of both the core tube and the 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 mixed structure.
