4 Identification of critical response of bilinear-hysteretic SDOF model with tuned inertial mass damper under long-duration ground motion through internal simulation monitoring
-
Izuru Takewaki
Abstract
In this paper, the critical (resonant) response of an elastic-plastic single-degree- of-freedom (SDOF) model with a tuned inertial mass damper is derived under a long-duration ground motion. This means a kind of system identification of nonlinear passive control structures through internal monitoring by numerical simulation. Tuned inertial mass dampers exhibit high seismic performance when optimally tuned to the natural period of the structure. However, if the structure shows an elastic-plastic response and the natural period fluctuates from the original one, the damper cannot guarantee its performance. A multi impulse introduced by Kojima and Takewaki [1, 2] is used as a representative of long-duration ground motions. This substitution allows us to evaluate the critical resonant response of the elastic-plastic SDOF model without iterative and time-consuming computation. Finally, the resonance curve of elastic-plastic SDOF models [2, 3] is extended to the nonlinear model with the tuned inertial mass damper, and it is demonstrated that the proposed evaluation method shows a good agreement with the result for the corresponding sinusoidal wave.
