The characteristics of slab-column connections were experimentally investigated. Eight slab-column specimens were tested under repeated lateral load simulating earthquakes. Major variables were : 1) the tensile reinforcement ratio, . 2) the arrangement of that reinforcement, 3) shear reinforcement. Based on the test results, cracking patterns and failure modes, load-deflection relations, effective width of slabs, deflection modes of slabs, average strain distributions of slabs measured by contact strain gage, distributions of flexural moment at slab critical section, α values defined by ACI 318-71-applied moment due to lateral load relations, ultimate shear strengths were described with tables and figures. Furthermore, inadequacies in the assumption of the design method in the ACI Code 318-71 were pointed out.
