| Abstrakt: |
Infinite life fatigue resistance of bolted single support bar modular bridge joint systems (MBJS) was recently evaluated by testing full-scale MBJS subassemblies at the ATLSS Engineering Research Centre of Lehigh University. The test results demonstrated that with adequate bolt pretension, the infinite life fatigue resistance of CB-SB connections in SSB MBJS can be classified as AASHTO Category B. The current AASHTO Specifications classify this detail as Category D. Based on analytical and experimental studies, revisions to the existing AASHTO Specifications for MBJS were proposed. |
