- Abstract
- In the report test results for experiments on two half-scale beam-to-column web moment connections are described. In the first experiment an innovative concept aimed at enhancing the ductility and strength of the connection by adding two pairs of reinforcing ribs was explored. In the second experiment the behavior of similar connections but without reinforcing ribs-a type that is common in practice-was evaluated. The new design was relatively simple to fabricate and the reinforced connection exhibited excellent strength and ductility characteristics. The results show that these moment connections are suitable for severe seismic service.
