CFT 柱與RC 版間因兩者材料的差異，對於複合式版柱之貫穿剪力強度的
計算方式並不明確。本研究之目的為CFT 柱-版之貫穿剪力強度及如何有效提
升其強度。本研究共提出3 種加強構件，配置於相同斷面之鋼管周圍用以提升
CFT 柱-版的貫穿剪力強度。其一，以鋼條板進行加強；其二，以角鋼所構成如
同柱冠的加強構件進行加強；其三，以槽鋼所構成如同隱藏式柱頭版的加強構
件進行加強。本研究共完成6 座版柱試體之載重試驗，根據試驗結果可得到下
列結論與建議：
實驗結果顯示：(1) CFT 柱-版的貫穿剪力強度大於相同柱斷面之RC 柱-
版。(2) 本研究提出3 種加強構件皆能有效提升CFT 柱-版貫穿剪力強度。(3)
依照建議對於版承載面合理的假設，以規範公式可以保守的評估CFT 柱-版、
以及配置加強構件之CFT 柱-版的貫穿剪力強度。(4) CFT 柱-版之鋼管與版的剪
力摩擦係數大於0.6。

The calculation of the punching shear strength of the CFT column-slab is not
clear due to the difference in material. The purpose of this study is to get the punching
shear strength of the CFT column-slab and how to effectively increase its strength. In
this study, three kinds of reinforcing members were proposed, which were arranged
around the tube of the same section to improve the punching shear strength of the
CFT column-slab. (a) It is reinforced with steel plate; (b) It is reinforced with which
made of angle steel and stiffener like column capital; (c) It is reinforced with which
made of channel steel and stiffener like invisible drop panel. In this study, the load test
of the six column-slab specimens was completed. According to the test results, the
following conclusions and recommendations can be obtained:
The experimental results show that: (1) The punching shear strength of the CFT
column-slab is greater than the RC column- slab in the same column section. (2) This
study proposes that all three kinds of reinforcing members can effectively improve the
CFT column-slab punching shear strength. (3) According to the recommendations for
the reasonable assumption of the bearing area, the CFT column-slab and which
arranged the reinforcing member can be evaluated conservatively by the formula of
code. (4) The coefficient of shear friction between the CFT tube and slab is greater
than 0.6.
