Uma abordagem alternativa para obtenção da classificação de solos da AASHTO usando redes neurais artificiais

Transportes, 2021
A prospecção e análise preliminar de solos para identificar a sua tendência de comportamento como subleito através da classificação da AASHTO, gera custos iniciais altos aos projetos rodoviários, os quais, muitas vezes, oneram o seu valor final, tendo em

Mechanics‐based model for cold joints in reinforced concrete members

Structural Concrete, EarlyView.
Abstract This study introduces a mechanics‐based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading. The model incorporates mechanisms such as interface slip and opening, aggregate interlock, clamping force, and dowel action of the reinforcing bars crossing the interface.

Proposing 3-DoF Model to Study of Mass Parameter Effects on Longitudinal Period in Base Isolated Bridges [PDF]

Journal of Structural and Construction Engineering, 2018
The effect of mass parameters on the natural vibration period of isolated bridges is discussable, especially in case of substructure mass components, because of the disagreement of different researchers about it.

Structural Health Monitoring of a Unidirectional Isolation Bridge: Bidirectional Seismic Behavior, Stochastic Model Updating, and Prediction

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 759-780, March 2026.
ABSTRACT Accurate mechanical characterization of civil engineering structures after construction remains challenging due to the unique complexities of each structure, including geometric configurations, imperfect design modeling assumptions, soil conditions, and pervasive uncertainties in actual operational environments. Leveraging actual measurements,

Fatigue Lifetime Assessment of HFMI‐Treated Welded Joints According to the Peak Stress Method

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 3, Page 790-819, March 2026.
ABSTRACT High‐frequency mechanical impact (HFMI) is an effective post‐weld treatment that enhances fatigue strength by inducing compressive residual stresses, localized strain hardening, and increasing weld toe radii. The peak stress method (PSM) was recently extended to evaluate the fatigue strength of HFMI‐treated steel joints under uniaxial loading ...
