碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 83 === Currently, the punching shear strengths of reinforced concrete
slabs with openings are calculated using the provisions of
Section 11.12.5 of ACI Building Code. However, the provisions
of Section 11.12.5 of ACI 318-89 are based on test results of
low-strength concrete slabs with openings. In recent years,
there is a trend to use high-strentgh concrete in construction,
therefore it becomes necessary to examine the applicability of
current ACI Code when applied to reinforced high-strength
concrete slabs with openings. In this study, thirty specimens
were tested . Variables included in this study are the concrete
strength , the type of opening and the flexural reinforcement
ratio. The test results of this study and results presented in
previous studies indicate that for both low-strength and high-
strength concrete slabs with openings, the punching shear
strengths calculated using the provision of ACI 318-89 are
overly conservative. Base on test results, the design
equations proposed by previous researchers are also carefully
examined in this study.
