Investigations into Expansion Joint Movement for Integral Abutment of Multi-Span Concrete Bridges

This project extends the work of a previous project for single-span bridges. The research will provide realistic data for multi-span bridge expansion joint design. The American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) code expansion joint movement guidance is conservative for parts of Colorado. Improved design guidance will save money, and result in lower maintenance needs and costs.
