Abstract:
Test data for interior flat-plate slab-column connections subjected to concentric gravity load and combined gravity and lateral loads were collected. The connection strength was evaluated using ACI Code design equations. From test data, equations for connection gravity load capacity as a function of concrete strength, slab reinforcement ratio and yield strength, and the ratio of column size to slab effective depth were developed. A model for strength of connections subjected to lateral load using a beam analogy concept that includes resistance from flexure, shear, and torsion at the critical section is proposed.
