Abstract
All of the BFP connections reached 5.0% total rotation and 3.0% plastic rotation without significant strength degradation. The participation of BFP connection components in the inelastic behavior depends upon the relative strength and strain hardening of BFP connection components. The slip behavior results in more energy dissipation for BFP connections. Experimental results have clearly demonstrated that capacity controlled by the net section fracture of the girder is lower than the full plastic bending capacity, which invalidates the current design provisions. The inelastic behavior of BFP connections can be modeled by using several flexural elements and rotational springs. At least two analytical models are needed to represent the behavior: pre-slip model and post-slip model. These analytical models provide a reasonable estimate for the initial stiffness and inelastic behavior of BFP connections.
