Abstract:The application method of friction energy dissipation in structural seismic strengthening is discussed.Taking an engineering project as an example, the seismic design of the structure is checked and the weak story is found with the help of TAT soft ware.The optimal parameter of the friction energy dissipation is designed based on genetic algorithm and the limitation of structural interstory displacement is satisfied under minor earthquake and major earthquake.
