利用單自由度等效線性系統簡易之特性,改善RC結構物進行非線性動力分析複雜及耗時之缺點。以等效線性法不需迭代之作法,估算非線性最大位移節省分析之時程。依循臺灣耐震設計規範,發展一套適合臺灣之等效線性法,以及使用單自由度非線性動力分析多組結構於一百組地震下之反應,判斷等效線性法之準確性;另外,由單自由度等效線性法將設計反應譜轉換衍生出韌性需求譜,其幫助工程師設計時能更快速的了解結構物之韌性需求。最後,因台灣耐震設計規範中,用途係數之訂定無特別透過可靠度相關運算,故對此進行研究並利用地震機率特性,期望能求得結構物於不同用途係數下之年破壞機率,探討其耐震可靠度。
To develop equivalent linearization method for Taiwan, this study performs nonlinear dynamic analysis in single degree of freedom on different structure with 100 records of earthquake ground motions and compare the accuracy with the results of equivalent linearization method. Furthermore, the ductility demand spectrum which help engineers to estimate the ductility demand of a structure can be developed by employing acceleration design spectrum and equivalent linearization method directly. In the Taiwan seismic design code, the importance factor is determined directly without any reliability calculation, therefore, by using the characteristic of seismic probability, annual failure probability under different importance factor are calculated and the seismic reliability are studied as well in this paper.
