Diatomaceous Soils and Advances in Geotechnical Engineering—Part I

open access: yesApplied Sciences, 2022
Diatoms are microscopic algae with a skeleton called a frustule, formed chiefly of silica, and are found in almost all aquatic environments and climatic conditions. Diatomaceous soils (DSs) originate from frustule sedimentation.

Study on Shear Resistance and Structural Performance of Corrugated Steel–Concrete Composite Deck

open access: yesApplied Sciences, 2023
This study looks into a new composite bridge deck structure that employs a corrugated steel plate as the base. The goal is to address the shortcomings of traditional deck-bearing capacity, stiffness, and stress performance.

Experimental Investigation of the Shear Resistance of Concrete Hinges Under a Biaxial Load

open access: yesSlovak Journal of Civil Engineering, 2020
Concrete hinges can withstand extremely high loads and rotations, while requiring only minimal maintenance. Their use is widespread, mainly in bridge construction, but they also find applications in the prefabrication of tunnel segments.

Experimental investigation on shear resistance of self-consolidating concrete beams

open access: yesRevista IBRACON de Estruturas e Materiais, 2019
Self-consolidating concrete stands out for its high fluidity and stability, which are obtained by the reduction of the coarse aggregate dimensions and content in the mixture and also by the addition of superplasticizer and viscosity modifiers.
