Research Report 175 Effects of multiple presence & monitoring period on bridge health monitoring

Published: | Category: Activity management , Research programme , Research & reports | Audience: General

Bridge health monitoring is a method of evaluating the ability of a bridge to perform its required task (also called fitness for purpose) by monitoring the response of the bridge to the traffic loads it has to withstand.

This report is stage 3 of a research project carried out between 1998 and 2000, that has involved the long-term health monitoring and fitness for purpose assessment of the Atiamuri Bridge over the Waikato River, on State Highway 1N between Tokoroa and Taupo, North Island of New Zealand.

The investigation had the principal purposes of investigating and refining the health monitoring methodology for New Zealand road bridges. Issues such as the necessary sample size, duration of monitoring, effect of multiple-presence events, and appropriate methodologies for determining the ultimate traffic load effect (UTLE) were investigated.
