The principles for lifecycle safety guarantee of engineering structures are proposed, and the conception is developed for developing the safety guarantee system by integrating the monitoring system, analysis system and maintenance system together on the basis of multi-sensor, distribution-measurement, data fusion and digital-signal-processor (DSP) technologies as well as three-dimensional (3D) fatigue fracture unified theory. As all the systems should work in situs and in real-time, micromation and integration are important. Damage detectability is introduced to clarify the relationship of life prediction and healthy monitoring or faulty diagnosis. The research work to realize the lifecycle safety guarantee system is summarized and perspectives for future efforts are outlined.
