A composition of simplified physics-based model with neural operator for trajectory-level seismic response predictions of structural systems
Jungho Kim, Sang-ri Yi, Ziqi Wang
Accurate prediction of nonlinear structural responses is essential for earthquake risk assessment and management. While high-fidelity nonlinear time history analysis provides the m…
Framework for uncertainty quantification of wave-structure interaction in a flume
Xiaoyuan Luo, Vijay Nandurdikar, Sangri-Yi +3
In this paper we propose a numerical procedure for the quantification of uncertainties in wave-structure interaction. We utilise the smoothed particle hydrodynamics (SPH) scheme fo…
Long-range Ising model for regional-scale seismic risk analysis
Sebin Oh, Sang-ri Yi, Ziqi Wang
This study introduces the long-range Ising model from statistical mechanics to the Performance-Based Earthquake Engineering (PBEE) framework for regional seismic damage analysis. T…
Dimensionality reduction can be used as a surrogate model for high-dimensional forward uncertainty quantification
Jungho Kim, Sang-ri Yi, Ziqi Wang
We introduce a method to construct a stochastic surrogate model from the results of dimensionality reduction in forward uncertainty quantification. The hypothesis is that the high-…
