本研究乃以試驗方法，針對鋼筋混凝土版之貫穿剪力強度做進一步的研究
並從試驗結果推導出更為合理且適用性較廣之經驗公式。目前鋼筋混凝土
版之貫穿剪力強度公式，一般皆以ACI[1]規範第 11．12節為設計依據。
因此式乃由一般強度之鋼筋混凝土版試驗推導所得，而由現有之文獻資料
指出，高強度混凝土版與一般強度混凝土版之貫穿剪力行為稍有差異。因
此，該式之適用性實有待做進一步探討之必要。

The design of punching shear of reinforced concrete slabs is
currently based on the provisions of Section 11.12 in ACI
318-89. The provisions of Section 11.12 in ACI Building Code
are entirely based on tests of normal-strength concrete slabs.
Therefore, it becomes necessary to examine the applicablility
of current ACI Code when applied to high-strength concrete
slabs. In this study,thirty-four specimens were tested.
Variables included were the concrete strength, the aspect ratio
and the reinforcement ratio. Based on test results in this
study and results presented in previous studies, an equation
which can more resonably predict the punching shear strength of
reinforced concrete slabs is proposed in this study.
