本研究根據過去試驗結果(Cheng 等學者, 2016、Wibowo, 2017)，已測試之四組試體(CCC-N-1.5、H60、CCC-V-1.0、CCC-D-0.5)為基礎，規劃並測試另外兩組高長比分別為1.5及1.0，且無腹版橫向鋼筋之低矮剪力牆試體，目的欲探討低矮剪力牆之腹版橫向鋼筋存在與否於往復載重行為之影響。所有試體之面內剪應力需求(Vmpr)一致，即試體於牆底發展可能彎矩強度Mpr所對應的正規化剪應力值，約為10√f'c(psi)(0.75√f'c(MPa)。根據實驗結果所得之結論顯示，沒有橫向鋼筋的試體其最大正規化剪應力有降低的趨勢，高長比1.5及1.0的兩組試體具有腹版橫向鋼筋的試體有更好的變形能力，且改變橫向鋼筋量會影響試體最後的破壞模式。

According to specimen H60 (Cheng, et al.) and CCC-N-1.5、CCC-V-1.0、CCC-D-0.5 (Wibowo, 2017) were test in the past. This paper evaluates the effects of horizontal web reinforcement on cyclic behavior of RC squat wall using test results of three pairs of specimens. Two specimens were tested by the authors while the other four were adopted from the existing researches. Each specimen pair was designed with approximately the same design parameters, except that uniformly distributed horizontal web reinforcement was provided in one specimen only. Shear stress demand, evaluated based on the shear associated with the development of flexural strength at the base, was approximately 10√f'c(psi)(0.75√f'c(MPa). According to the experimental results, the normalized peak shear stress of the specimen without uniformly distributed horizontal web reinforcement has a decreasing trend. Test results showed that specimens of 1.5 and 1.0 aspect ratio with uniformly distributed horizontal web reinforcement exhibited the larger deformation capacity than the specimens without it. Changing the amount of horizontal web reinforcement will affect the final failure mode of the specimen.
