性能設計を目的とした線形二次レギュレータで制御される一質点系建物の構造系・制御系の同時最適化

抄録

A simultaneous optimization procedure is formulated in order to match desired performances of a building. Design variables of structural and control parts of a building with a linear quadratic regulator (LQR) controller are optimized simultaneously. The natural period and the damping factor of the LQR-controlled system are calculated based on eigenvalue analysis. Design response spectra are used to consider input ground motion and to calculate the maximum control force as well as maximum responses. As an example, this optimization procedure is applied to the seismic strengthening of a traditional wooden building by considering reduction of its displacement and acceleration responses.
