Real‐Time Hybrid Fire Simulation on Steel Frames: Coupling Strategy and Parameter Effects

Understanding and modelling the complex interactions and load redistribution mechanisms of steel structures under fire conditions remains difficult even today. In fact, structural fire safety research and application still lack concrete methods that accurately capture phenomena in structural systems. While large‐scale...

Explicit Method for the Simulation of the Out-of-Plane Collapse of Unreinforced Masonry Walls: Influence of Hourglass Control, Damping, and Element Formulation

Nonlinear dynamic FEM analyses of unreinforced masonry (URM) must address convergence difficulties in implicit solutions, conditional stability in explicit solutions, and numerical artifacts related to element integration. This study compares implicit and explicit time-integration procedures using a homogenised three-d...

APPLIED ELEMENT ANALYSIS OF BLAST RESILIENCE AND PROGRESSIVE COLLAPSE OF FRP-STRENGTHENED RC BUILDING FRAMES

The increasing risk of accidental and/or intentional explosions has highlighted the need for reliable computational tools capable of predicting the damage evolution and collapse behavior of reinforced concrete (RC) structures subjected to blast loading. Although conventional finite element approaches can accurately cap...

Progressive collapse resistance of composite steel‐concrete structures following local damage due to fire

Over the last decades, significant work has been developed worldwide into the field of structural robustness under extreme events. According to EN 1990, the design situations relevant to structural robustness refer to accidental actions, like blast, gas explosion, impact, fire, or localized failure. Although some of th...

FATIGUE ASSESSMENT OF STEEL-CONCRETE COMPOSITE BRIDGES USING NONLINEAR FINITE ELEMENT ANALYSIS AND NEURAL NETWORK

A data-driven framework for fatigue assessment of steel-concrete composite bridges that integrates nonlinear finite element analysis (FEA) with artificial neural networks (ANN) is presented, enabling efficient exploration of load paths and cycle-dependent deterioration.

Coupled analytical and finite element investigation of dynamic and cyclic response in cracked functionally graded beams

Offshore and marine structures increasingly utilise Functionally Graded Materials (FGMs) because of their superior stiffness and enhanced resistance to damage under combined vibration and cyclic loading induced by waves, wind and operational conditions. This study presents a combined analytical and finite element inv...
