Analytical Investigations and Design Implications of Seismic Response of a Two-Span ABC Bridge System

Various connections and prefabricated components have been developed and investigated under seismic loading in the past decade. Component studies have been essential in understanding the local behavior of connections and have provided invaluable information. However, to determine the adequacy of the connections in a realistic bridge, the connections along with prefabricated elements should be integrated and studied in a bridge system. Through a study at UNR funded by the ABC-UTC Cycle 2 funding allocation, a two-span bridge system with steel superstructure, full-depth precast deck panels, SDCL (simple for dead, continuous for live) connections, and a two-column bent that integrates precast columns with pocket and grouted duct connections is under construction for testing on shake tables at UNR. The objective of the study to is to generate test data on interaction among various components and connections under biaxial simulated earthquake. Approximately 300 channels of data are collected on this bridge. The scope of the current project allows only for design, shake table testing, processing of data, and preliminary analysis. Extensive analytical studies of the bridge model are essential to maximize the benefits of the shake table tests and translate the results into practical design methods.
