近年來,隔震技術已廣泛應用於全台灣各地之建築上,尤其台南市近十年隔震大樓如雨春筍蓬勃發展,台灣位處板塊運動交界處,地震頻繁發生是最自然的天然振動臺場域,想要達到保護結構物或設備與降低其損壞,想必需要經過很多真實結構物經歷真實地震考驗,而研究上,礙於研究成本和實驗空間等問題,即發展出即時複合試驗,原理為將主結構數值化並寫入電腦,由電腦內之主結構數值模型計算主結構受地震力作用之反應,再由振動台將主結構頂層之反應呈現,真實次結構則是放置於振動台上,如此即可利用模擬之主結構與真實次結構互動,以得到與真實狀況接近之結果。近年來,隔震墊開發商或學術研究領域都積極進行隔震技術開發與監測,並透過國家地震中心BATS、MAST、大振動臺進行實驗,但是操作複合試驗需要經過適當的教育訓練,以及對硬體設備、回授系統具有充分的實驗經驗,否則極容易在實驗過程中產生非預期行為造成設備損壞,故本文研究重點為開發成大振動臺數位式傳輸迴路複合試驗,成大振動臺與國家地震中心使用相同的傳輸方法進行實驗,可讓成大振動臺成為教育訓練場域,以利即時複合試驗技術人才培育與技術測試。
In recent years, seismic isolation technology has been widely applied to buildings throughout Taiwan. In the past decade, many buildings in Tainan City have adopted seismic isolation structures. Taiwan is located at the intersection of tectonic plates, making earthquakes a frequent natural occurrence. To protect structures or equipment and reduce their damage, it is crucial to subject real structures to real earthquake tests. However, due to research costs and experimental space limitations, real-time hybrid testing has been developed. The principle involves digitizing the main structure and inputting it into a computer. The computer's numerical model calculates the main structure's response to seismic forces, which is then replicated by a shake table presenting the response at the top level of the main structure. The real substructure is placed on the shake table. This way, the interaction between the simulated main structure and the real substructure can provide results that closely approximate real-world conditions. In recent years, developers of seismic isolation pads and academic research fields have actively engaged in the development and monitoring of seismic isolation technology. They utilize the National Center for Research on Earthquake Engineering (NCREE) facilities such as BEAT, MAST, and the large shake table for hybrid testing. However, operating hybrid tests requires formal education and training, as well as extensive experimental experience with hardware equipment and feedback systems. Without this, unexpected behavior can easily occur during experiments, causing damage to equipment. Therefore, this study focuses on developing the digital transmission loop hybrid testing for the shake table at National Cheng Kung University (NCKU). This enables the NCKU shake table to use the same transmission method as the National Center for Research on Earthquake Engineering, making it an excellent training field.
