碩士 === 國立臺灣科技大學 === 營建工程系 === 88 === Currently, the punching shear strength of reinforced concrete slabs is calculated using the provisions of Section 11.12 of ACI 318-95. However, the provisions of Section 11.12 of ACI Building Code are primarily based on test results of reinforced low-strength concrete slabs loaded through a rectangular column. Therefore, it becomes necessary to examine the applicability of current ACI Code when applied to reinforced high-strength concrete slabs loaded through a L-shape column. In this study, eighteen specimens were tested to investigate the punching shear behavior of reinforced concrete slabs loaded through a L-shape column. Variables included in this study are the concrete strength, the flexural reinforcement ratio and the bo/d ratio.Based on test results in this study, the applicability of current design equations when applied to reinforced concrete slabs loaded through a L-shape column are carefully examined.
