近年來台灣在歷經921大地震的重傷後，結構物的耐震能力比起過去格外的受到重視，而鋼筋混凝土所構成的剪力牆也正廣泛的被應用在建築結構上以作為耐震構材之一；剪力牆或者鑲嵌於柱樑構架內的RC牆在結構耐震安全上所呈現的主要功能為提升結構的勁度與消能，但是在傳統剪力牆的結構行為趨向脆性結構行為，且其載重-變形遲滯圈的行為也明顯顯示了擠壓現象（pinching -effect）而降低消能。因此，如何提升剪力牆之結構韌性與消能行為實為國內、外研究學者所亟欲解決之問題。
　　本文研究目的在探求剪力牆－構架之結構韌性行為，找出良好的韌性消能機制並藉由有限元素法的理論分析驗證實驗所得結果；另外則探究純構架系統與剪力牆系統之間的差異並比較不同鋼筋形式排列對韌性消能的影響。鋼筋混凝土剪力牆主要承受的為剪力，不同於梁、柱所承受的撓曲作用，但是由於混凝土材料的特性，鋼筋混凝土結構受力後容易產生裂縫，最終造成開裂破壞，這即為剪力牆受力行為的主要破壞機制。
本文實驗規劃旨在探求出一高韌性的剪力牆行為機制，以便地震力屆臨時達到良好的消能作用及耐震行為，因此實驗規劃中除了比較純構架系統與含邊柱剪力牆系統的差異外，並針對剪力牆的主應力分佈作一扇型配筋形式的改良以求得到良好的消能行為。故試體的原型系統共分：(a)構架系統（柱樑系統）(b)傳統配筋含邊柱剪力牆系統(c)45度斜向配筋含邊柱剪力牆系統(d)扇形配筋含邊柱剪力牆系統，利用側向反覆載重加載至破壞之實驗結果配合OpenSees (Open System for Earthquake Engineering Simulation)有限元素分析，探討鋼筋混凝土含牆構架之開裂載重、降伏載重、極限載重與結構韌性等牆體力學性質並比較其差異。

　The Chi-Chi earthquake (September 21, 1999) in Taiwan induced severe damage of school buildings. The investigations on the failure of buildings show that these damaged buildings are mainly caused by shear failure of short column, insufficient walls, and too small column cross-section. RC Shear walls have been recognized as efficient earthquake resistance elements. Framed shear walls are extensively used as the components of earthquake resistance buildings. However, the conventional shear walls, which the reinforcements are in vertical and horizontal directions, frequently possess pinching-effect in the load-displacement curves. The improvement of conventional shear wall to reduce the pinching-effect sounds an essential research.
The OpenSees (Open System for Earthquake Engineering Simulation) finite element model is adopted to analyze the experimental results. These specimens include framed shear walls with high-, middle-, low-rise framed shear walls, pure frames, pure walls, and high seismic performance framed walls. The reinforcements of high seismic performance walls were designed with 45° reinforcements, 45° and boundary vertical reinforcements, and hybrid conventional and 45° reinforcements.
　The experimental results showed that the failure of high-rise shear walls is flexural; their ductility factors are greater than those of low-rise shear walls; their displacements are also greater. The middle-rise shear walls failed by a combination of both flexure and shear. The experimental results also show that the crack load, yield load, and limit load are superior for specimens with higher concrete strength and frame with wall. The numerical solutions agree well with the experimental results.
The results show that the pinching-effect, which frequently existed in the conventional shear walls, is remarkably improved in the new design high seismic performance walls. The larger steel ratio in the shear walls with 45° reinforcements induces less pinching-effect. The structural behavior is highly dependent on the layout of reinforcements of walls. The new design shear wall possesses high potential to improve the seismic performance of buildings, and the proposed numerical model will be a fundamental of model-based simulation of concrete structures.
