Sensitivity analysis of fluid-structure interaction using the PFEM

International Conference on Applications of Statistics and Probability (12th : 2015 : Vancouver, B.C.)

Sensitivity analysis of fluid-structure interaction (FSI) simulations provides an important tool for assessing the reliability and performance of coastal infrastructure subjected to storm and tsunami hazards. As a preliminary step for gradient-based applications in reliability, optimization,system identification, and performance-based engineering of coastal infrastructure, the direct differentiation method (DDM) is applied to FSI simulations using the particle finite element method (PFEM) to compute sensitivities of simulated FSI response with respect to uncertain parameters of the structural and fluid domains that are solved in a monolithic system via the PFEM. Due to geometric nonlinearity of the free-surface flow, geometric sensitivity of the fluid is considered in the governing equations of the DDM along with sensitivity of material nonlinear response in the structural domain. An example application shows sensitivity to load and resistance variables of a reinforced concrete frame subjected to tsunami loading with open and closed first story design configurations.
