Calibration & Refinement of Illinois' Earthquake Resisting System Bridge Design Methodology

The key work stages include: Stage 1: Refinement and calibration of the first "fuse" capacity and seismic redundancy level that exists between superstructure and substructure through a series of experiments and analyses of bearing subassemblies. Stage 2: Computational simulation of response of bridge systems, including documentation of the progression of damage in the bridge; required seat widths; anticipated peak forces in the substructure; and evaluation of changes in stiffness or strength during the seismic event. Stage 3: Refinement of strength reduction factors and R-factors used for design of typical Illinois bridges and development of a simplified approach for pushover analysis.
