本文蒐集過去研究團隊的測試結果，有系統的比較八組高寬比為1.0或1.5之低矮剪力牆試體往復載重行為，評估高強度材料應用於低矮剪力牆之可行性。分析結果指出，所有試體的最大側力可由計算撓曲強度合理評估，而試體極限變形能力隨著正規化剪應力需求增加而下降。在相同剪應力需求下，使用高強度鋼筋對高寬比1.0試體之變形能力增加較為明顯；在相同配筋量下，使用高強度混凝土、降低正規化剪應力需求，可以增加試體極限變形能力。

This study systematically compares test results of 8 specimens to evaluate the potential of using high-strength materials in RC squat walls. All specimens with h_w/l_w of either 1.0 or 1.5 were tested under lateral displacement reversals by the same research group. Analytical results indicate that peak strength of all test specimens can be reasonably estimated by the nominal flexural strength. Specimen deformation capacity decreases as the normalized shear stress demand increases. If shear stress demand is similar, the use of high-strength steel improves deformation capacity of specimens with h_w/l_w of 1.0 more obviously. For specimens having the same reinforcement layout, the use of high-strength concrete slightly reduces normalized shear stress demand and results in larger specimen deformation capacity.
