FIELD PERFORMANCE OF TIMBER BRIDGES: 12. CHRISTIAN HOLLOW STRESS-LAMINATED BOX BEAM BRIDGE

The Christian Hollow bridge was constructed in January 1992 in Steuben County, New York. The bridge is a single span, stress laminated box beam superstructure, 9.1 m long, 9.8 m wide and 502 mm deep (30 ft long, 32 ft wide, and 19-3/4 in. deep) The performance of the bridge was continuously monitored for 28 months, beginning shortly after installation. Performance monitoring involved gathering and analyzing data relative to the wood moisture content, force level in the stressing bars, vertical bridge creep, and behavior under static load conditions. In addition, comprehensive visual inspections were conducted to assess the condition of the overall structure. Based on field evaluations, the bridge is performing well with no structural or serviceability deficiencies.
