內政部建築研究所於台南成功大學歸仁校區內興建大型戶外研究設施，包含實驗平台以及單層樓實尺寸鋼構架實驗屋。實驗平台為長18公尺、寬12公尺之RC結構，又分為上部與下部結構，中間由12顆劦承精密所製之CC-SB150盤式支承墊作為連結，上部結構乘載著實尺寸鋼構架實驗屋，長、寬12公尺，單一樓層高約4公尺。計畫之目的為研究複合性災害，因此設施主要以地震及火災為考量而設計，將使用成功大學土木系所擁有之MK-155U離心質量激振系統作為外部激振力進行強制振動，並對實尺寸鋼構架實驗屋之局部梁、柱進行火燒，藉以模擬複合性災害發生時結構物所產生之行為變化。
本文記載計畫興建相關實驗設施。本文於實驗規劃章節中詳細說明如何利用MK-155U激振系統對火害前後鋼構屋進行系統掃頻，並說明各次實驗流程及實驗後訊號的處理的方法。另外，推討雙自由度系統的雙曲線等值線性隔震數值模型，利用雙自由度系統之轉換函數，解釋實驗的趨勢與現象，且與SAP2000模型進行擬合驗證。此外，對非線性摩擦隔震元件進行測試與探討。SAP2000主要針對現階段局部小梁與混凝土版受火害前後進行火害模擬，觀察火害後對系統參數的影響。最後，由此次實驗的經驗，對未來實驗提供適當建議。

Taiwan is located in a seismically active zone, on the Pacific Ring of Fire. Earthquakes occur frequently in this area, often extending to other disasters. Fire disasters are the most frequent consequences, due to the electrical equipment inside the buildings. We call a situation compound disaster when the main disaster brings about secondary disasters. In the literature we can find full-scale buildings and outdoor shaking tables to create reality scenarios. When the experimental data is close to real, the study results are more credible; however the incurred cost is relatively high. Accordingly, a group of domestic researchers jointly established this project. This project includes a full-scale steel structure, a base-isolated platform, and a forced vibration system configured on the platform. The forced vibration system called MK-155U Eccentric Mass Vibrator System belongs to NCKU. The isolation system uses 12 pot bearings with low friction coefficients, facilitating a low-cost shaking table. For our experimentation we used this full-scale steel structure to conduct the fire experiment. In our study we also establish a procedure of system identification for full-scale steel building and low-friction pot bearings. We use a mathematical model taken from SAP2000 and Matlab for identify this building . The model is a 2-DOF mathematical model with isolated bearings and full-scale steel building to emulate the natural frequency change of the structure. We compare the use of a 2-DOF linear and a nonlinear model for simulating the sweep experiment. By changing the isolation layer’s friction coefficients, we accomplish what the isolation pad’s coefficient of friction and full-scale building’s natural frequency.
