AB  - The objective of this research is to develop a numerical model of one widely used bolted beam splice connection
that dissipates energy through structural damping. The reference experimental setup is carefully designed to
obtain the highly nonlinear dynamic response due to the suddenly released load. The fact that the monolithic
beam with welded connection has a linear response is utilized for the initial calibration of the numerical and
experimental models. Then, the numerical model of bolted beam splice connection is verified and adopted
through an iterative process. The influences of time and spatial integration, bolt load application, element
type, contact formulation, bulk viscosity, and mass scaling are discussed. A special attention is given to the
load application and load release functions. After the verification, the Abaqus/Explicit numerical model is
validated through the comparison with experimental data, where an appropriate friction coefficient is adopted.
It is demonstrated that the nonlinear structural damping occurs due to the complex micro slip behavior at the
contact interface.
