| Abstract: | General mechanic differences and methods of dynamic response analysis of RC structure characterized by abrupt change in horizontal connection stiffness are discussed. For structure of Putian Center of Radio, Film and TV, complicated modals and stress concentration resulted from abrupt change in horizontal connection stiffness are revealed by FEM.Different connective plans located in place of abrupt change in horizontal connection stiffness have effects on structural dynamic properties and seismic response. |
