Abstract

The continuous collection and storage of data describing the state of a structure provides a wide range of advantages over conventional structural maintenance systems. The most significant of these include the overall increase in the safety of the monitored application as well as a potential long term reduction in maintenance costs as the need for intrusive and costly inspection routines is reduced. This is true for many industries including Rail where track inspections often require closure of the line and a significant manual intervention. Recent developments in electronic sensors and data acquisition and transmission systems have led to an increase in momentum in the development of state-of-the-art technology in the field of Structural Integrity Monitoring. One such system is the new Stress Memory Technology (SMT), developed by FIOSTEC Ltd. and University College London. This consists of a self-contained hand-sized monitoring unit which, when attached to the surface of the structure, passively senses and records the occurrence of predefined structurally significant events. This paper presents the application and results of field trials carried out in conjunction with AMEC SPIE Rail to investigate the feasibility of SMT for monitoring of the Stress Free Temperatures (SFT) in Continuously Welded Rail (CWR). Initial results indicate a high level of accuracy, repeatability and sensitivity of the SMT technology and demonstrate that the systems are sufficiently accurate to monitor stresses in both applications. The use of Reliability Based Analysis as part of a complete monitoring strategy is also investigated and results are presented based on the preliminary field trials.
