- Abstract
- In reliability analysis, the correlation between the primary failure mode of a frame structure and other failure modes is very complicated. At present, there are a number of issues associated with the implementation of reliability analysis, including the complex calculation procedure, the low calculation efficiency, and the difficulty in identifying the primary failure mode, etc. Following the framework of reliability analysis for hybrid systems, the reliability of a two-story frame structure is investigated. The internal force distribution in all structural members is analyzed using the numerical method of Finite Element Method (FEM). The critical structural element is calculated, which can help to evaluate the primary failure mode of the frame structure. Once local failure occurs, the internal force redistributes in the system. The pattern of progressive failure of frame structure is then analyzed. The developed numerical model can provide the real-time performance for the structure, which is further employed to conduct reliability analysis. This study demonstrates that the reliability analysis method for hybrid system can reflect the true performance of the structure more realistically.
