Uncertainty-Based Climate-Adaptive Design Optimization of Embedded Footing
Publication: Geo-Risk 2023
ABSTRACT
This study aims to develop a quantitative framework to optimize embedded footing performance subjected to extreme historical climate events with respect to the uncertainties associated with site-specific soil and climatic parameters. The proposed method was applied to a semi-arid climate site in Riverside, California, as a case study. By performing the optimization procedure, it is found that the proposed climate-adaptive design method provides a better optimal design for the embedded footing in comparison with the conventional method. The optimization result indicates that the footing width significantly drops from 4.72 m to 3.79 m for the design at the Riverside site, compared to the conventional method. Regarding the total construction cost, the optimal design from the proposed method for the Riverside site shows 19% lower cost, compared to the one from the conventional method.
