- Abstract
To improve the development of life-cycle multihazard-based design theory for high-performance structures in China, the research progress of this field was summarized and the research framework was systematically set up. The researches on the probabilistic occurrence models of individual hazard and multiple hazards were elaborated. The analytical models concerning the environmental effects on the time-variant deterioration of materials and structural component were summarized by taking the carbonization corrosion and wind induced fatigue as examples, which were conducive to guide the life-cycle performance assessment of high-performance structures subjected to multiple hazards. Moreover, the research status of the fragility analysis and the life-cycle cost based optimization design approach for high-performance structures were discussed in detail. The combined effects of multiple hazards and the lifetime deterioration of structural performance, which are neglected in the traditional specifications, can be rationally included in the life-cycle multihazard-based structural analysis and design methodology, which is of great significance for the development of building structural design.
