【Abstract】 Seismic response of buildings with SMA dampers under strong earthquakes are calculated by using a program written by the authors for calculating the nonlinear responses of structures. The numerical studies for SDOF structures with SMA dampers and MDOF structures with SMA dampers are conducted. The influence of SMA dampers on the reduction effectiveness is studied through nu- merical examples and the best values for the parameters of SMA dampers are suggested. Finally, the distribution of SMA dampers on MDOF buildings is also discussed.更多还原
