以半導體及TFT LCD光電產業為首的高科技產業乃我國經濟上極為重要之產業,由九二一地震﹙1999年﹚及三三一地震﹙2002年﹚經驗中,新竹地區震度並不大,然而竹科業者卻蒙受巨大之半成品(work in process)、設備及營運中斷(business interruption)等損失,就耐震力而言,只要200gal以上的振動加速度,即可能導致設備無法修復的損壞,若能使用有效的防震措施,以減少地震能量之輸入,必能減少高科技產業因地震所造成的損失。
有鑑於此,本研究考慮利用非古典阻尼的觀念,推導速度型黏性阻尼器應用於高科技廠房之減震設計,以降低其結構及非結構之地震加速度及位移反應,並進行動力分析驗證該設計公式之正確性,以擬訂出一套可行的補強設計或新結構設計方法。
The semiconductor and TFT LCD industries are two of the most important industries in Taiwan. The seismic vulnerability of the factories observed during the 1999 Taiwan Chi-Chi earthquake and the 2000 Taiwan 331 earthquake has raised the attention to the seismic retrofit of these factories. Based on the past experiences, the industries have been bothered by the loss of work-in-process and the business interruption due to small earthquakes. This is because a great amount of vibration-sensitive equipment may shut down automatically during small earthquake excitations. Furthermore, it is believed that major loss may result when the peak ground acceleration at the site exceeds 0.2g.
Based on the aforementioned need, it is proposed in this study to use viscous dampers to seismically retrofit the semiconductor factories. However, due to the difficulties of the construction in the clean room, it is proposed that the dampers to be installed in between the shell structure and the exterior structure of the factory such that the operation of the factory may be least interfered by the construction considering the micro-vibration and cleanness issues of the clean room. Corresponding to this retrofit method, the structure with the viscous dampers is modeled using non-classical damping theory to derive the design formulas of viscous dampers, while the classical damping theory is considered to be inappropriate in this application. The proposed design formulas are validated by a few numerical simulations.
