| Abstract: |
High Load Multirotational (HLMR) Disk Bearings have been a staple in highway bridge construction for over 50 years, boasting an impressive track record across various structures. Commonly found in light rail bridges throughout North America, an exemplary case study is their application in the Washington Metropolitan Area Transit Authority (WMATA) System. Here, HLMR Disk Bearings have been implemented in the new Silver Line's concrete bridges and used to retrofit steel plate girder bridges on the Orange Line, replacing failed bronze spherical and steel rocker bearings. This paper will explore the usage of disk bearings in light rail bridge projects, focusing on both new constructions and retrofitting applications. It will delve into design and testing requirements with the aim of educating engineers about the advantages and reliability of this innovative technology. |
