Hydromechanical modeling of unsaturated soils considering compaction effects on soil physical and hydraulic properties
(Springer Science and Business Media Deutschland GmbH, 2024)
Acceso abierto
This study presents a methodology that includes hydraulic and mechanical constitutive relationships for modeling the complex volumetric behavior of unsaturated soils. The mechanical relationships are based on the generalized ...
A hemivariational damageable elastoplastic vertex-spring model for masonry analysis
(SAGE Publications Inc., 2024)
Acceso restringido
This work is an intermediate step towards the extension of a recently proposed block-based model for masonry structures, which was based on a hemivariational approach and inspired from granular micromechanics. Here, ...
Influence of fibres on the resilient modulus and expansion of clayey subgrade soils
(Taylor and Francis, 2024)
Acceso abierto
Expansive clayey soils at the subgrade level of roads and highways in different cities can affect the performance and durability of pavements. This increases the need for maintenance and conservation work, leading to higher ...
Effect of mixed alkali ions on the structural and spectroscopic properties of Nd3+ doped silicate glasses
(Elsevier, 2024)
Acceso abierto
In the present work the effect of alkali ions (Li, Na, K) and the combination of them on structural and spectroscopic properties of Nd3+ doped silicate glasses were systematically investigated. Results from infrared and ...
Using UAVs and Photogrammetry in Bathymetric Surveys in Shallow Waters
(MDPI, 2023)
Acceso abierto
The use of UAV (unmanned aerial vehicle) platforms and photogrammetry in bathymetric surveys has been established as a technological advancement that allows these activities to be conducted safely, more affordably, and at ...
Influence of Synthetic Fibers on the Flexural Properties of Concrete: Prediction of Toughness as a Function of Volume, Slenderness Ratio and Elastic Modulus of Fibers
(MDPI, 2023)
Acceso abierto
The construction industry requires concrete with adequate post-cracking behavior for applications such as tunnels, bridges, and pavements. For this reason, polypropylene macrofibers are used, which are synthetic fibers ...
Analysis of delays and cost overruns of road construction projects in the Colombian Caribbean Region
(Nicolaus Copernicus University, 2023)
Acceso abierto
Construction projects are constantly threatened by delays and cost overruns that might compromise their viability. Th us, identifying the leading causes of these issues based on the experience of experienced professionals ...
Simplified methodological approach for estimating the mean repair time of building portfolios directed to the development of seismic resilience policies, based on the distribution of resources
(Springer, 2023)
Acceso restringido
Recovery from a catastrophic seismic event is dependent on multiple aspects involving resilience capacity. Disaster Risk Reduction management includes the development of policies focused on the preparedness to overcome the ...
A cost-benefit analysis for the appraisal of social and market prices in the probabilistic seismic risk assessment of building portfolios: A methodology for the evaluation of disaster risk reduction programs
(Elsevier, 2023)
Acceso restringido
A cost-benefit analysis can be a milestone for the probabilistic seismic risk assessment of building portfolios. This approach appraises social, economic, and technical aspects as evaluation criteria, becoming a reliable ...
