Abstract |
In this study, the nonlinear time history analysis of seismic retrofitted structures with TS damper for seven ground motion records was conducted for the purpose of verifying the seismic strengthening effect of TS seismic retrofitting method. Through comparison of the interstory drift ratio and the energy dissipation amount of the non - reinforced structure obtained and those of retrofitted structures with TS damper from the nonlinear time history analysis, the interstory drift ratio was reduced by about 30% and the amount of energy dissipation through the structure was halved. As a result, it was confirmed that the damping performance of the TS seismic retrofitting method is excellent.
