摘要：

The effect of superimposed slab loading on the behavior of interior slab-column connections was studied by testing two-bay slab-column subassemblies. Each subassembly consisted of one interior and two exterior connections. Three identical slab-column subassemblies were subjected to the same cyclic lateral displacement routine while each supported a different superimposed slab load. The tests show that increased slab load substantially reduces both the unbalanced moment capacity and the lateral drift capacity of the connections. A limiting shear stress is suggested to insure adequate drift capacity for interior slab-column connections. The test results are compared with present ACI 318-83 Building Code provisions and ACI Committee 352 recommendations for design of slab-column connections.
