ABSTRACT

Design criteria of slab-column connections in the ACI Building Code (2011) were mostly developed based from experimental results of interior connections. When dealing with corner slab-column connections, supplementary documents published by Joint ACI-ASCE Committee 352 and Joint ACI-ASCE Committee 421 provide better explanations than the ACI Building Code (2011) and become useful references for practical engineers. However, different design values can be obtained using the recommended analytical approaches provided by each document. A summary of this issue is presented in this research. With the design parameters discussed in this research, ACI 421 generally provides higher punching shear demand than with ACI Building Code but the discrepancy can be effectively minimized by increasing the slab thickness. Connection with rectangular column attracts larger moment transfer along the stronger axis.
