Impact of Response Spectra Definitions and Direct Displacement-Based Design Simplification for Multi-Span Bridges

Research to reevaluate impact of response spectra definitions on the design of multi-span bridges by conducting computational research to develop recommendations for hazard levels. Aims to develop simplifications to the direct displacement-based design approach for multi-span bridges that will facilitate implementation into bridge design practice. Work will include the following deliverables: Literature Review, Computations/analysis for AK multi-span Bridges, design results and recommendations for final report
