A bending moment M<SUB>u</SUB> transferred at slab-column connection is resisted at the slab critical section by flexure and shear. The ACI 318-05 Building Code gives an empirical equation for the fraction γ<SUB>v</SUB> of the moment M<SUB>u</SUB> to be transferred by shear at the slab critical section at d/2 from the column face. The equation is based on tests of interior slab-column connections without shear reinforcement. In addition, in the design of flat-plate buildings subjected to seismic load, providing adequate punching shear strength for the slab is often a problem. In order to investigate the data eight test specimens were examined. The specimens were divided into two types which according to its tendon arrangement and bottom reinforcement existence and nonexistence. Each subassemblies were subjected to the same cyclic lateral displacement routine while each supported a different superimposed slab load. The test shows that increased slab load substantially reduces both the unbalanced moment capacity and the lateral drift capacity of the connection. Especially, the specimens with the bottom reinforcement existence and nonexistence, appears remarkable differences. Studies also show that the code equation for γ<SUB>v</SUB> does not apply to all cases.
The purpose of this study is to compare the test results with present ACI 318-05 Building Code provisions for design of slab-column connections and with the analysis of the experimental data for a new limitation of strength equation without shear reinforcement and bottom reinforcement.
