Project 4.16: Investigating the Long-Term Durability of CFRP Repairs for Bridges Under Environmental Conditions

Investigating the Long-Term Durability of CFRP Repairs for Bridges Under Environmental Conditions Project 4.16 Project Summary Carbon fiber-reinforced polymers (CFRP) have been widely used for bridge repair and strengthening because of their high strength-to-weight ratio, corrosion resistance, and ease of installation. However, the long-term durability of CFRP repairs under harsh environmental conditions remains unclear. Accumulated […]

Project 1.21:Efficient and Cost-effective Rating of Critical Members of Steel Truss Railroad Bridges Supported by Field Test Data

Efficient and Cost-effective Rating of Critical Members of Steel Truss Railroad Bridges Supported by Field Test Data Project 1.21 Project Summary With the current rate of infrastructure aging, the railroad bridges have been placed in the second plan for immediate replacement. However, highway and energy resources have shown a great need for prioritized capital investment. […]

Project 1.23: Wireless Joint Monitoring for Large Movement Expansion Joints for Highway Bridge Resilience

Wireless Joint Monitoring for Large Movement Expansion Joints for Highway Bridge Resilience Project 1.23 Project Summary The primary objective of the proposed engineering project is to monitor a large movement expansion joint of a multi-span highway bridge using the developed real-time wireless sensor system from the previous project.
