INTELLIGENT MONITORING OF JACK ARCH STRUCTURES: THE RESULTS OF A PRELIMINARY STUDY

A cast iron beam, instrumented with deflection gauges, strain gauges and two acoustic monitoring systems, was subjected to a series of load cycles. The aim of the test programme was to determine whether acoustic emission (AE) techniques could be used to form the basis of an intelligent monitoring system. The results support the view that AE was generated by a load-related mechanism - most likely due to micro-cracking of the cast iron - and so AE techniques might indeed form the basis of a monitoring system, but further work is required to develop a practical system.
