확률적인 에너지의 크기를 제한하는 구조물의 능동제어 ( Bounded Stochastic Energy Control Building Structure under Nonstationary Random Loads )

Earthquake, one of the external loads, transfers great concentrated energy into the structure in a few early seconds which influences the structural behavior. The external energy increases the internal energy of the dynamic system and can induce failure of the system when excessed above a certain limit. This study is on the minimum-time optimal control of the system energy. External loads are expressed in stochastic form and change of the system energy is prescribed by the designer to preserve the system energy under the upper limit eventually to save the cost.
