The mediocre man of José Ingenieros [PDF]

open access: yes, 2017
Poner la vida al servicio de un Ideal, es la perspectiva idealista que propone José Ingenieros en su obra clásica de 1913 El hombre mediocre, donde establece los lineamientos generales de una “psicología del ideal” en la que funda su “sociología moral”.

Explainable hybrid stacking ensemble method for hard rock pillar stability prediction and engineering applications

open access: yesDeep Underground Science and Engineering, EarlyView.
This research proposes an interpretable hybrid stacking ensemble framework, optimized by the Sparrow Search Algorithm, to enhance hard rock pillar stability prediction. By integrating six machine learning models—k‐nearest neighbors, support vector machines, random forests, Gradient Boosting Decision Tree, eXtreme Gradient Boosting, and Light Gradient ...

Exploring the potential of Textile Reinforced Concrete for corrosion‐insensitive retaining walls

open access: yesStructural Concrete, EarlyView.
Abstract In a context where durability concerns, particularly the corrosion of steel reinforcement, remain a critical challenge for conventional reinforced concrete structures under severe exposure, Textile Reinforced Concrete (TRC) is emerging as a promising alternative.

Durability performance of a high‐performance fiber‐reinforced concrete for bridge applications

open access: yesStructural Concrete, EarlyView.
Abstract This paper investigates the durability performance of a coarse‐aggregate high‐performance fiber‐reinforced concrete (HPFRC) developed as a cost‐efficient material solution for precast bridge applications. A comprehensive experimental program was conducted to assess the resistance of the material to the principal deterioration mechanisms ...

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

open access: yesStructural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

Evaluating structural resistance and updating modeling uncertainties through testing

open access: yesStructural Concrete, EarlyView.
Abstract The aging of infrastructure necessitates a robust and rational methodology for the assessment of existing structures. Design codes provide general models which cover different design scenarios and are thus overly conservative. Also, such design approaches lack field data and, if applied directly to existing works, often lead to unnecessarily ...
