Abstract

The use of integral or semi-integral abutments in bridges has the potential to reduce maintenance and increase service life by preventing surface water and deicing chemicals from seeping in and causing deterioration, especially at bridge ends. However, design specifications for these abutments vary, and researchers sought to understand which design details would achieve the expected structural integrity and performance under service loads. Inspection and instrumentation of bridges in the field, paired with numerical assessments, provided firsthand information that will help engineers evaluate the long-term impact of abutment choices, taking into consideration a range of design factors.
