Development of a BDD-based methodology to estimate importance measures in seismic probabilistic risk assessment

Nuclear Engineering and Technology
Probabilistic risk assessment (PRA) evaluates the core damage frequency (CDF) as the plant risk by considering failure events such as failure of structures, systems, and components (SSCs) and failure of operator's actions.

Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]

, 2014
Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.

A Bottom‐Up Design Framework for Multifunctional Lattice Metamaterials

Advanced Science, EarlyView.
This study introduces a generative AI framework for designing multifunctional lattice metamaterials. The method combines 3D Gaussian voxel generation with deep learning, enabling greater design freedom and structural performance. The optimized lattice metamaterials achieve enhanced energy absorption by 40–200% compared to conventional structures and ...
