Abstract Details

2007, MS, University of Cincinnati, Engineering : Civil Engineering.
The complex moment-rotation behavior of bolted moment resisting connections requires advanced modeling techniques for the purposes of analysis and design. A model is presented that predicts the behavior of the combined slip and bearing mechanisms in T-Stub connections or bolted connections of similar geometry. A monotonic, multi-linear response is presented which accounts for variable initial bolt locations. A cyclic model is developed based upon the monotonic response and predetermined loading and unloading stiffness. The cyclic model accounts for hysteretic pinching due to degradation in connection slip load. Several functions that predict slip load decay are evaluated based upon cyclic energy dissipation. The model is validated using the results of 40 T-Stub component tests conducted at the Georgia Institute of Technology. The monotonic model is best implemented assuming a linear distribution of initial bolt position. It was found that a linear function based upon cumulative deformation is the best predictor of slip load decay.
