Online monitoring system for structures at elevated temperature

Absztrakt

OLMOST-HT project aimed to develop an integrated hardware and software system for on-line and on-site measurement of structure displacements in most critical regions in order to prevent failure due to flaw or fatigue occurred by degradation mechanism as creep, thermal ageing, and hydrogen embitterment on high temperature. Due to the unknown condition and the high consequences of any failure means that the operational risk can be extraordinary high. To prevent failure, maintenance in time requires special dedicated monitoring techniques. Having proper online global and local displacement and deformation data comparison can be done between the estimated and real data and decision can be. In this paper the previous experience of the OLMOST-HT monitoring system is presented. This study describes the main laboratory test, the trial of the monitoring system and a finite element case study of a catalytic reactor.
