Abstract: A life-cycle performance intelligent-sensing and degradation warning system and method for concrete structures are disclosed. The warning system comprises a main control module, a multifunctional sensor module, an anti-theft module and a critical warning module. Environmental parameters in concrete are monitored by the multifunctional sensor module, and the remaining service life of a concrete structure is accurately predicted through a life prediction model according to the temperature, humidity, chloride ion concentration and pH at different depths, and a critical chloride ion concentration and a structure stress status that are dynamically obtained.
