近年來在世界各地發生許多災害,而這些災害並非只有單一地震如此,而是地震後所產生更大的海嘯災害,不僅造成受害者財物上損失也提醒著人們必須做出預防的動作,及早做好防範之準備,避免生命財產受到侵害,所以本研究探討地震和海嘯產生的複合型災害。此海嘯研究對於三層樓及二層樓進行分析,海嘯之參數(溢淹高度、流速及通量)及結構之參數(形狀、高度及迎向海嘯之面積),進行水理分析,求取海嘯作用於結構之衝擊力,再將衝擊力等相關受力轉化為等效之海嘯作用力。在目前業界上由於各學者對於結構物補強之評估方法不同,相對於模擬結果也有所差異,為了方便提供介紹模擬補強方法,所以將目前常用之補強工法結合程式TEASPA(設定塑鉸)模擬入ETABS,本研究對擴柱補強、翼牆補強、鋼板包覆補強、鋼斜撐補強、外加構架補強進行模擬分析,分析對於這些評估方法的結果與實驗的討論,且分析得到基底剪力和屋頂位移關係曲線圖,該分析結果可用來比較評估方法對於耐震能力的差異性。
In recent years, there are many disasters happened around the world. Sometimes after an earthquake, a tsunami induced by the previous earthquake caused more serious damage. This study focused on the assessment and retrofitting of complex disaster with earthquake and tsunami for reinforced concrete structures. In the currently, many scholars provided different assessment methods for structural retrofitting. Therefore, those assessment results are usually different. In order to improve it, this study introduced simulate methods for general retrofitting methods. The simulate method combined TEASPA method with plastic hinge definitions into ETABS program. Moreover, this study also introduced the comparison results of the simulation and the experiment with the RC jacketing retrofitting, the wing wall retrofitting, the steel jacketing retrofitting, the steel bracing retrofitting, and the external frame retrofitting with shear walls.
