Abstract:
The effects of the column dimensions on the punching shear strength andductility of slab-column connections are investigated. For this purpose, five edgecolumn-slab connections were tested. The parameters were the column aspect ratioand the perimeter length of the critical shear section. The test results in addition to testresults from the literature for interior columns are compared with the shear strengthprovisions of the ACI Code. The validity of applying the shear strength equationsoriginally developed for interior connections is investigated, in particular with respect tothe effect of the column dimensions.
