Stochastic Emulation using Generalized Stratified Sampling for Performance-Based Risk Optimization of Structures

Metamodels are instrumental in reducing the computational burden associated with nested reliability analyses and optimization loops in Performance-Based Risk Optimization (PBRO) of structures under stochastic loads.
