為避免設備物在遭受地震時產生大量滑移及傾倒,並提升設備物在地震中的耐震能力,本研究發展一磁性基座(MCN, magnetic connector)。當設備物安裝基座時,透過磁性基座中間兩極的磁吸力,使設備物在小震中不致傾倒或損害,在地震強度較大時,磁性基座的磁力能有效減少滑移幅度並降低傾倒的可能性。研究中為充分了解MCN的特性,使之能發揮適當的抗震功能,特別針對磁性基座進行多項元件試驗,透過試驗結果建立電腦模型,分析磁性基座與設備物的關係,並與振動台實驗相互比較分析,藉以取得磁性基座在應用上的特性與使用限制,使得磁性基座將來能更廣泛應用在設備物的抗震機制。
研究過程中,考慮固定樓版的效益及趨勢較為保守的方式,依據Ishiyama傾覆性公式提出的兩種預測公式,進行公式修正,以符合本研究藉由磁力作為防傾機制,變因中增加有磁力的垂直向作用,並據之設計磁性基座的耐震強度。本研究設計發展的磁性基座特性試驗及振動台實驗,均以醫療用冰箱作為主要實驗對象,將四組磁性基座安裝於冰箱底部,並將安裝磁性基座的設備物固定於鋼筋混凝土樓版面上,分析基座破壞時的加速度值。另外,在電腦模擬時,破壞分析則以側向力作為控制因子,模擬中將近斷層及遠域地震歷時各自放大,使Link的力與位移圖出現平台時,視為磁性基座產生破壞。模擬結果顯示,加速度大於0.92g時,磁性基座將會產生位移甚至造成破壞,本研究以此作為較保守的設計準則。在計算磁性基座的破壞位移量分析中,本研究建議以側推力由最大值Pu降至0.8Pu時的位移量(約為19mm)作為破壞位移量,使磁性基座不致在低於設計位移量時產生破壞。
The Medical Freezer(MF) and several equipment of hospital were slipped and overturned in the Hualien Earthquake (20180206). According to the Code, the hospital is one of the important building in the numerous types of architecture, and increasing the aseismic capability of the non-structure components which attached to the hospital can reduce the damage. To resolve the phenomenon, the MF was conducted as the main test specimen, and the magnetic connection (MCN) was installed on its base to test the response in different time history (near fault, far field and the top floor recording on the hospital) in order to verify the validity and rationality of formula. Based on the final results of this study, the MF was resetting favorably due to the normal force of magnetic which were installed in the MCN and the spring on corner of the plate also provided effective constraint to avoid its slipping down. And the MCN was slipped when the PGA exceeded 0.4g. Compared with the MF which excluded the MCN, the final results of this study might be a reference to further research.
