Physics-informed surrogate modeling for reliability-based robust design optimization of the external load factor in bolted joints under uncertainty

The external load factor (χ) is a key parameter affecting the performance and reliability of bolted joints. This study presents an integrated framework combining experimental measurement, physics-informed surrogate modeling, and reliability-based robust design optimization (RBRDO) to analyze and optimize χ under uncert...

Probabilistic approach to rating the mechanical characteristics of concrete in finite element modeling of reinforced concrete structures

The article addresses the pressing issue of transitioning from deterministic design methods for reinforced concrete structures to probabilistic models that require high precision in defining the initial mechanical characteristics of concrete. The authors propose a scientifically grounded approach to standard...

Engineering safe structures: recent advances in structural reliability modelling

This paper reviews advances over the last decade in the field of computational structural reliability modelling. The discussion is focused on problems of time-variant/time-invariant reliability at the component level. Three broad classes of problems are considered: (a) time-invariant reliability problems involving stat...

Understanding masonry behaviour through DEM: influence of mortar quality and pre-existing damage under compression

Experimental identification and robust optimization of spindle–bearing systems with reliability constraints

Multi-probability constrained reliability-based topology optimization using volume control

To overcome the limitation of deterministic topology optimization (DTO) which ignores uncertainties, this paper proposes a multi-probability-constrained reliability-based topology optimization (MRBTO) model for structures under multiple displacement constraints. The MRBTO model treats loads and material prop...
