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. In addition, during warning analysis, a targeted correction method is designed for acquired data, and temperature and pH correction is carried out for real-time monitoring data of the chloride ion sensor to further guarantee the accuracy of monitoring data, such that scientific references are provided for durability evaluation, protection and restoration of the structure.

Abstract: A frustum embedded fabricated composite protective structure is provided, including a restraint frame, a back plate, an infill block and a buffer block. The restraint frame is provided with a plurality of mounting holes matching with the shape of the infill block, the restraint frame is arranged on the back plate, the infill block is in a frustum shape. The buffer block and the infill block are installed in the mounting hole of the restraint frame, the buffer block is arranged on the smaller end of the infill block, and the infill block is wedged into the mounting hole of the restraint frame through a wedge surface mating. Because this protective structure is assembled by multiple restraint frames and infill blocks, under the prestress restraint of partition blocks, the damage range after penetration or explosion will be significantly reduced, and it can withstand multiple blows.

Abstract: The present disclosure relates to an oxidation-induced shape memory fiber comprising a tension-bearing core material and/or a tension-bearing core material coated with an antioxidative coating, and an oxidizable pressure-bearing coating. The oxidizable pressure-bearing coating is coated outside the tension-bearing core material and/or the tension-bearing core material coated with an antioxidative coating; the oxidizable pressure-bearing coating is in compressive stress state and/or the tension-bearing core material coated with an antioxidative coating and the oxidizable pressure-bearing coating are in tension-compression balance state. The disclosure also relates to preparation and application thereof, the preparation is: reserving anchoring end, exerting tension force on tension-bearing core material and/or tension-bearing core material coated with an antioxidative coating, followed by coating oxidizable pressure-bearing coating thereon. The oxidation-induced shape memory fiber is applicable to high temperature oxidation environment.
