Monitoring Structural Health of Penang Bridge Using Online System

摘要

Penang Bridge was completed in 1985 as the main linkway between mainland Peninsular Malaysiarnand the island of Penang. The approach spans are currently being widened from 2-lane dualrncarriageway to 3-lane dual carriageway including an additional motorcycle lane on eachrncarriageway due to huge increase in traffic volumes since the bridge was originally completed.rnThere is a need to monitor the structural health condition during construction activities for anyrnpossible short-term effects and also post-construction for long-term bridge performance. Arnmonitoring system for settlement, tilt and vibration is implemented at Penang Bridge to monitorrnstructural health. Data from sensors positioned along the full-length of the bridge are picked-up andrntransmitted to the data-logger system via wireless modem and this allows real-time monitoring to berncarried out remotely at the control centre. The system has proven to be able to pick-up any majorrnchanges in the structural condition of the bridge and provide ample warning, especially during therncurrent construction stage. Once the widening works has been completed, the system will remain asrna permanent means of monitoring the long-term structural health of the bridge.
