On-Site Monitoring of the Moisture Content of Bridge Decks Made of Nail-Laminated Timbers
Publication: Journal of Structural Engineering
Volume 147, Issue 7
Abstract
This study summarizes the moisture content (MC) monitoring results of two nail-laminated timber (NLT) bridge decks in New Brunswick, Canada. The MC monitoring systems were installed in the NLT decks of two newly built bridges, Clark Mill Pond and Shikatehawk No. 5, in New Brunswick, recording the MC through the electrical resistance (ER) method. The calibration test was conducted to correlate the ER values () and MC values (%). It was found that the MC values varied from 9.9% to 18.2% and 12.8% to 19.7% for Clark Mill Pond Bridge over 239 days and Shikatehawk No. 5 Bidge over 189 days, respectively. Based upon these MC monitoring data, the NLT deck surfaces could likely not be prone to rotting caused by biotic attack during the monitoring period.
