摘 要 本研究主要在探討含鋼線網剪力筋柱同時受固定軸力及動態反
覆橫力作用下之撓曲行為。其中以傳統#3竹節筋取代冷拉鋼線製作成WWF
。試體尺寸為300×300×4500mm。實驗變數為混凝土強度、載重型式、箍
筋量、箍筋種類、WWF擺置方式與軸力大小。共計製作十支試體,所有試
體皆設計成撓曲破壞。試驗結果可歸納如下: 1.ACI規範對柱件極限撓曲
強度的預估略為保守。 2.動態反覆荷重並不會降低柱試體的極限撓曲強
度,但會大 大降低柱試體的延展性。 3.箍筋量愈多,柱件的延展性
及能量消散能力愈好。 4.含鋼線網剪力筋柱在極限撓曲強度、延展性、
裂縫控制、 強度與勁度遞減情形方面與傳統橫箍柱相當;在能量消散
能力上則比傳統橫箍柱略佳。故含鋼線網剪力筋柱應能應 用於工程上
。 5.WWF箍筋橫擺在極限撓曲強度、延展性、強度與勁度折減 等方面
的表現都與WWF箍筋直擺相當,但在能量消散指標 方面則比WWF箍筋直
擺略差。 6.承受高軸力(0.4P0)之柱件,明顯在延展性、強度與勁
度折減、能量消散能力上,比承受低軸力(0.2P0)柱件的 表現差,但
裂縫控制則較佳。

Abstract The
purpose of this study is to investigate the flexural behaviorof
concrete columns with welded wire fabric as shear reinforcement
under constant axial load and cyclic lateral load . A total of
ten column specimens were made in this study . The size of
specimens was300mm×300mm×4500mm . The variables included were
concrete strength、loading type、amount of transverse
reinforcement、type of transversereinforcement、level of axial
load and arrangement of transverse reinforcement . The
results showed that strengths predicted by ACI Code were
conservative . Cyclic loading on column would not reduce the
maximumstrength but would reduce the ductility tremendously .
Flexural strength、 ductility、crack control、strength and
stiffness degradation of columns with welded wire fabric were
about the same as columns withconventional transverse
reinforcement . Capability of energy dissipationof columns with
WWF was higher than that of conventional columns .WWFcan be
adopted in concrete columns due to its construction ease .
