Abstract |
The aim of this study is to investigate punching shear strength of exterior connections in the flat plate structure with rectangular column. To inspect the effect of column aspect ratios on the punching shear behavior, eight specimens for exterior connection were made and tested. In this experimental program the length of critical perimeter was kept constant, while column aspect ratio varied from 2.0 to 4.5. Two levels of concrete strength and slab reinforcement ratio were also considered. As the column aspect ratio increased, the punching shear strengths are decreased. The decrement of punching shear strength was small in specimens with high aspect ratio of column.
