鋼筋混凝土剪力牆具高側向勁度和高強度的特性，藉此控制結構位移，是有效地抵抗地震力之主要構件，因此在耐震設計和耐震補強中廣泛應用，然而，高側向勁度的特性也致使牆在震後常是結構中破壞嚴重的部分，故了解其力量-變形關係，方能掌握結構耐震性能評估之準確性。
本研究蒐集13座高長比介於1.0至1.5之間的低矮型剪力牆測試結果，所有試體測試方式皆在無軸力下承受側向反復載重，且試體外部變形一致由光學儀器量測。剪力牆試體總變形量，藉各別計算之變形分量加總而得，其中分為牆體撓曲變形 (Flexural Deformation)、牆體剪力變形 (Shear Deformation)、應變穿透或稱主筋滑移變形 (Strain Penetration or Slip Deformation)、以及牆底剪力滑移變形 (Sliding Deformation)；同樣地，依變形分量各別進行參數分析，發展主筋降伏前之勁度模型。
本研究建議適用於低矮型剪力牆的四線性側力-位移曲線，包括剪力開裂點、降伏點、最大強度點、以及極限位移點，經與試驗結果比對，在降伏點之位移有合理之預測結果。提供之方法可供耐震性能評估使用，期望研究成果能應用於實際結構設計，供工程師在結構設計上參考應用。

Reinforced concrete shear walls have the characteristics of high lateral stiffness and high strength to control the structural displacement, which is the main component to effectively resist the seismic force, and therefore are commonly used in seismic design and seismic retrofitting. However, the characteristics of high lateral stiffness also result in the wall often being the part of the structure that is severely damaged after an earthquake. Therefore, it is important to realize the force-displacement relationship in order to understand the accuracy of the assessment of the seismic performance of the structure.
This study collected test results from 13 low-rise shear wall specimens with height-to-length ratios ranging from 1.0 to 1.5. All specimens were subjected to lateral cyclic loading without axial load, and the external deformations were measured using optical instruments. The total deformation of the shear wall specimens was obtained by summing up the individual deformation components, including flexural deformation, shear deformation, slip deformation, and sliding deformation. Likewise, parameter analysis was conducted for each deformation component to develop a model of the stiffness of the longitudinal reinforcement before it yielded.
The force-displacement curve was proposed for low-rise shear walls, including shear cracking point, yielding point, peak strength point, and ultimate displacement point. After comparing with the test results, the displacements at the yield point are reasonably predicted. In addition to the seismic performance evaluation, it is expected that the research results can be applied to the actual structural design for engineers' reference in structural design.
