ABSTRACT
The development of LMS is a systematic approach for the organisation and execution of all activities, which belong to the stages of planning, assessment, construction, maintenance and monitoring. The purpose of a LMS is to identify potential impairments at an early state and to forecast the development of the structure’s condition in order to enable an economically optimised and sustainable structure maintenance. Elemental components of a LMS are:
– Probabilistic lifetime assessment procedures for the decisive mechanisms of deterioration
– Periodic condition data gathering beginning with a so-called ‘‘Birth-Certificate’’
– Application of monitoring-systems for a continuous condition assessment
– Improvement of the lifetime prognosis on the basis of surveyed data
– Probabilistic models for assessing the durability of maintenance measures
Because of large and unavoidable scatters on side of both the exposures and the resistances equally probabilistic assessments must be adapted.
