The behavior of a particular double tee flange-to-flange connector was investigated experimentally under in-plane load conditions. The connector consisted of a steel plate with two fillet-welded reinforcing bars embedded in 2 in. (50 mm) thick concrete slabs. Ten tests were conducted by applying a variety of loading conditions. Test results showed that the connector had a dependable and predictable strength under both monotonic and cyclic loading. Its deformation capacity depended on the type of applied loading. Under monotonic loading, moderate to high levels of deformation ductility were observed. Under cyclic load reversals, however, the deformation capacity and ductility of the connector were limited. Based on the test results, the performance of the connector is evaluated and criteria for future testing of similar connectors are presented.
