本論文主要在提供工程師一個便捷又觀念清楚之評估方法，不須經過特殊的電腦程式，利用常見、通用的辦公室軟體，建立一套表格化的評估模式，探討既有鋼筋混凝土建築物之耐震能力。 以本文使用之力法（國內評估法及紐西蘭力法）與位移法（紐西蘭位法）之評估方式而論，均以構架或桿件之位移韌性為基礎，建立各自判斷耐震能力之依據，就實用性而言，力法較為簡便，發展之理論也較為成熟，適用於一般使用對象；若是對於價值性及精密性要求較高者，應以位法較為適用。 利用國內評估法作補強時，不可只以最後之耐震能力值作為評估，更應注意勿使韌性比過低而產生脆性破壞。至於位移法所採用的位移設計反應譜，應建立更多數據資料，以為精確之使用。 This study was aimed at providing a sample and clear procedure for seismic assessment. Neglecting specially analytical computer programs to discuss the seismic capacity of the existing reinforcement concrete buildings. For the methods of force (internal and New Zealand) and displacement (New Zealand), both base on the ductility of the structural members to judge for the seismic resistance of buildings. Practically, the theory of the force-based method is more convenient and mature than displacement-based method. However, the displacement-based method can offer a more precise result, which is often used recently. When using the Taiwan document to strengthen or retrofit, engineers need care not only the factor of the seismic capacity, but also that too lower ductility ratio will produce the brittle failure. As for the elastic displacement spectrum, more data to proof the application to displacement-based method is needed.
