|Title:||Simplified Design Procedure for Hybrid Precast Concrete Connections|
|Published:||February 01, 1996|
|Abstract:||A rational design procedure is presented to compute the probable moment, the nominal moment, and the story drift capacities of a hybrid precast moment-resisting beam-to-column connection. The hybrid connections consist of mild steel which is used to dissipate energy by yielding and high strength prestressing steel which is used to provide the shear resistance through friction developed at the beam-column interface by the post-tensioning force. The design procedure is based on three 1/3-scale hydrid precast beam-to-column connections tested at the National Institute of Standards and Technology (NIST). The simplified procedure relies on the stress-strain behavior of mild steel up to its ultimate strength and is based on equilibrium equations at the beam-column joint. The appendices include a commentary of the design procedure, proposed evaluation criterion for this hybrid connection, sample calculations using the design procedure, and other calculations used to develop the design criterion.|
