- Abstract
Experience from past earthquakes has shown that beamtocolumn connections play a critical role in the survival of reinforced concrete momentresisting frame buildings. It is thus important to develop design procedures that will ensure a satisfactory performance of connections during an earthquake. The current practice for the design of connections has evolved from laboratory testing of a large number of beamtocolumn connections subassemblies. However, most of these tests did not include a slab, which, in a real building, is invariably an integral part of the framing system. Recently, some concern has been shown on the effect of the presence of a slab on the behavior of connections. The main objective of this investigation was to study the effect of the presence of a slab on the behavior of exterior beamtocolumn connections. A total of six threequarter scale beamtocolumn connection subassemblies were tested under a simulated earthquaketype loading. The primary test variable was the width of the floor slab. The test results show the slab to have a significant effect on the strength, stiffness, and energy dissipation characteristics of connections and strongly suggest that ignoring the presence of a slab in the design of connections may not be appropriate.
