摘要: 我國經1999年921集集大地震的洗禮後,造成數千人傷亡、許多房屋倒塌及公共建設損毀,至今仍有些結構物尚未完全修復,使得國人無不更加體悟到地震所帶來的影響及防震之重要性。國內工程界逐漸重視消能裝置對結構物的影響,消能元件被視為加強結構物耐震能力的額外裝置,但無可避免於地震過後會產生殘變形及無法使結構物恢復至原來位置,使修繕工作增加困難度,而近年來有學者提倡利用預力鋼腱之預力作用來降低結構物之變形。本文乃利用SAP2000數值分析,探討應用預力鋼腱之特性加裝在建築結構物上,降低樓房受地震力作用下所造成的破壞及過大的位移,進而大量提升其耐震能力之可行性,經由大量之例題結果比較,找出建築結構物裝設預力鋼腱之適當位置、數量、角度與尺寸,使得材料成本降低,以達到最小成本的目標,並利用阻尼器具消能的特性搭配預力鋼腱在建築結構物之抗震能力上以達相輔相成的效果。
Taiwan is located in pan pacific earthquake zone and is vulnerable to earthquakes from time to time. Earthquakes caused many damages to bridges, buildings, infrastructures and lives. This study uses energy dissipation and restoring devices to reduce the damages and displacements under the earthquake force. Dampers are also used to improve the performance. SAP2000 was used for analysis. The base shear, lateral deflection, and yielding are compared for the buildings with and without these mechanisms.
