台灣高科技廠房無塵室中,普遍以庫板牆系統作為空間分割隔間牆。然而於台南美濃地震開始,發現庫板隔間牆系統會在地震時產生面外方向破壞,造成高科技廠房無塵室失效停擺,造成巨大的經濟損失。
以往研究少針對庫板牆面外方向進行抗震研究,故本論文先針對庫板牆系統面外方向的靜態方向進行試驗,透過單向靜態試驗,了解不同設置下各位移階段中的強度與破壞機制。根據靜態實驗結果,以ANSYS有限元素法模型建立數值模擬,模擬彈性階段強度與預測第一挫曲點發生值。
動態分析部分,基於靜態分析所得有限元素法模型,並與2021於國震進行的足尺振動台試驗所得數據做為比對基礎,驗證動態模型的準確性。最後由此動態模型,提供基於天花板振動頻率與加速度的破壞預測線。
This study is based on observations of cleanroom partition wall failure in a hi-tech factory after an earthquake. The majority of cleanroom partition wall damage occurs due to out-of-plane failure resulting from screw failure between the top aluminum rail and the partition wall. During an earthquake, the partition wall itself remains elastic. Based on the data from out-of-plane push-over and full-scale shake table experiments, we have developed a reasonable static and transient FEA model. Using this model, we have also developed a damage prediction method based on measuring ceiling acceleration.
1. Through out-of-plane push-over experiments, we discovered that the L-shape reinforcement now used by hi-tech factories can enhance the link between the aluminum rail and partition wall. We also collected performance data for different screw installations.
2. Based on the FEA model and screw shear capacity, we can establish a ceiling acceleration-frequency failure prediction curve by inputting different accelerations and frequencies.
3. By observing the relationship between ceiling acceleration and frequency, raising the stiffness of ceiling system can help cleanroom partition. The effect of different reinforcement of ceiling system to partition wall remains a developable research direction.
