前人已證明將多項式變曲率隔震系統架設於振動台上,藉由直接量測隔震系統層間總剪力回授至主結構系統之數學模型,計算主結構樓板絕對位移反應並以此為命令發送至振動台,藉由此即時互制作用之混合實驗確實可模擬出隔震系統於真實震波作用下,主結構樓板上隔震系統之反應,並將真實振動台實驗簡化並取代。本文進一步將混合實驗推廣至被動控制摩擦質量阻尼系統上,首先以振動台實驗測試摩擦調諧質量阻尼器(FTMD)於高阻尼與低阻尼控制下相較於主結構系統無控制下之減振效果,證實FTMD系統被動控制確實可降低主結構系統受震波作用之反應。其次,將主結構系統簡化為數學模型,直接量測FTMD系統層間總剪力回授計算下一步主結構系統反應,並發送命令至振動台,使振動台可模擬出主結構系統於震波作用下絕對位移的反應,以此混合實驗重現FTMD系統於高阻尼與低阻尼控制下振動台實驗之反應。由本文混合實驗結果與振動台實驗數據比較結果證實,無論FTMD系統高阻尼與低阻尼控制下皆可以混合實驗重現振動台實驗時,FTMD系統裝設於主結構系統上之反應。由此可證明本混合實驗之架構不僅可重現隔震系統於振動台實驗下的反應,透過混合實驗模擬實驗元件與主結構系統間之互制反應,更可將混合實驗推展至被動控制摩擦質量阻尼系統上。因此可證明本混合實驗架構於結構實驗之發展性,取代傳統之振動台實驗,並可簡化複雜之數值模擬推導,為未來具相當發展性之結構實驗方式。
The friction-type tuned mass damper system (FTMD) is adopted in this thesis as the target for implementing the hybrid testing technique. Firstly, the shaking table tests of the FTMD controlled by high/low friction setups are conducted. The vibration suppression of the main structure equipped with the FTMD subjected to earthquake loading can be investigated and ensured. Secondly, the main structure is replaced by its numerical model and is embedded inside the hybrid testing configuration. The total shear force estimated from the inertial force calculated from the measured acceleration is fed back into the simulation part to find the absolute displacement command of the main structure. The shaking table is then adopted as the test bed of the hybrid testing to behave like the main structure and to interact with the equipped FTMD system. The test results of both hybrid tests and their corresponding shaking table tests illustrate similar control performance of the FTMD. Therefore, the hybrid testing technique can be extended to the friction-type control devices
