Lessons from Biaxial Shake Table Studies of a Two-Span ABC Bridge System with Socket Connections

Lessons from Biaxial Shake Table Studies of a Two-Span ABC Bridge System with Socket Connections is a technical learning program focused on experimental insights from full-system, biaxial shake table testing of an Accelerated Bridge Construction (ABC) two-span bridge with socket connections. Through a clear, practice-oriented review of test setup, instrumentation, loading protocols, and observed response, participants will examine how socket-connected substructures and superstructures behave under multi-directional earthquake demands. The program highlights key findings on global system performance, connection behavior, force transfer mechanisms, damage progression, and residual capacity—translating experimental results into actionable lessons for analysis, design, detailing, and performance-based evaluation of ABC bridge systems. Designed for bridge engineers, researchers, and advanced students, this program supports better-informed decisions on seismic resilience, constructability, and connection design for precast bridge applications.
