現今的地震設計法以強度設計法為主，其缺點在於其無法準確預測地震響應。因此人們開始發展性能化設計法，該法將預先設定的結構性能目標配合不同的地震層級當作設計依據。性能化設計的關鍵在於是否能準確定的定義性能極限狀態，並且必須要能適用於不同設計參數的建築物。本研究的目標是提出RC結構牆的位移預測模型，並與結構性能目標結合。本文首先將定義不同的性能目標以及性能極限狀態。接下來建立移預測模型，此步驟必須仰賴有限軟體產生大量不同設計參數的模型牆，並進行地震模擬以得到數據。最後將數據進行回歸，得到位移預測模型，並與現有的結構牆受反覆載重的實驗數據進行驗證。

The current building design codes are generally based on a strength-based design philosophy. A building designed according to such approaches has unpredictable seismic responses. Performance-based design approaches, which are recognized as advanced design methods for the next generation, allow engineers to design a building with the pre-determined structural performance objectives under varying seismic hazard levels. A key element to a successful performance-based design is an adequately defined framework of performance limit states. In addition, a direct approach to accurately identify the performance limit states of structures with different designs is also necessary when implementing the performance-based design. The object of this article is to propose a model for predicting the displacement demands associated with the performance limit states of RC structural walls. The model is developed using regression analysis on the extensive seismic responses obtained using 3D finite element RC structural wall models. Existing experimental results of RC structural walls under cyclic loading are employed to validate the proposed model. The comparisons between the experimental results and the predicted solutions show good agreements.
