摘 要
本研究主要係針對含高拉力剪力筋混凝土柱受反覆載重下之剪力強度進行
分析研究, 藉以瞭解高拉力剪力筋運用在混凝土柱時之適用性。本次
試驗共製作5根含高拉力剪 力筋RC柱及2根含傳統剪力筋RC柱,試體
採三分點加載,試驗之變數包括混凝土強度 、軸力、剪力筋量及繫
筋之有無等。除了探討含高拉力剪力筋混凝土柱之剪力行為 外,並
驗證ACI 95 Code之適用性。試驗結果顯示,承受反覆載重作用之高拉力
腹筋 柱,其剪力開裂強度與一般的傳統腹筋柱之剪力開裂強度相差
無幾。而其極限剪力 強度則較一般傳統腹筋柱高。此外,由於鋼線
本身的延展性很高,故所有試體均無 剪力筋被拉斷的情形發生。而
破壞模式則均為混凝土壓碎破壞。比較試驗結果可發 現,剪力開裂
強度(Vcr)及極限剪力強度(Vn)均隨混凝土強度愈高、軸壓力愈大
而強度愈高。但剪力筋量的增加雖Vcr並無明顯變化,卻能增加剪力筋之
剪力強度(Vs) ,因而提高Vn值。至於在剪力筋所提供之Vs方面,則是
高拉力剪力筋柱中所含剪力筋 效益高於傳統腹筋柱,且ACI規範對於
高拉力剪力筋柱中所含剪力筋之Vs值的計算略顯 保守。而混凝土強度
的提高與軸向力的增加對剪力筋效益而言並無太大的幫助。此外 ,對
照試驗值與ACI規範之剪力強度計算值得知,ACI 95Code 之剪力強度計算
公式略 顯保守。

Abstract
The purpose of this study is to investigate the shear behavior
of reinforced concrete columns with high strength shear
reinforcement under low cyclic axial force. A total of
seven column specimens were made in this study. Five of the
specimens contained high strength shear reinforcement while the
other two con -tained conventional shear reinforcement.
The parameters included in this study were concrete
strength , axial load , cross ties , amount of shear
reinforcement. The results showed that shear strengths at
cracking of column with high strength shear reinforcement
are not higher then those of column with conventional shear
reinforcement. The ultimate shear strengths of columns with high
strength shear reinforcement were higher than that of
conventional column. Both strengths at cracking and
ultimate of columns increased with concrete strength , axial
force , while reducing shear span ratio increased the
shear strengths. Efficiency of high strength shear
reinforcement was higher than conventional shear reinforcement.
Shear strength of ACI 318-95 Code provision is too
conservatively.
