Abstract:
Tests of five large-scale rectangular edge-column slab connections are reported. Two specimens were uniaxially laterally loaded, two more specimens were biaxially laterally loaded, and the fifth specimen was tested under gravity load only. The main objective of the experiments was to investigate the effects of column rectangularity, varying magnitudes of gravity loading, as well as cyclic biaxial lateral loading on the connection strength, stiffness, ductility, and drift capacity. Biaxial cyclic lateral loading was found to severely reduce the strength, stiffness, ductility, and drift capacity of slabcolumn connections with high column rectangularity ratios. A limit on gravity loads imposed on biaxially laterally loaded rectangularcolumn slab connections with an aspect ratio of 5 is proposed to be 0.3Vc to ensure that the minimum 1.5% drift ratio can be achieved in both directions. Finally, the strength of rectangular edge-column slab connections under gravity and biaxial cyclic lateral loading are assessed according to the ACI procedure.
