Delaying the Occurrence of Bar Buckling in RC Columns Confined with SRG Jacketing

open access: yesApplied Sciences, 2023
This paper investigates experimentally the structural performance of substandard reinforced concrete (RC) short columns confined with steel-reinforced grout (SRG) jackets under monotonically increasing uniaxial compression.

Multi‐Property Machine Learning Models to Accelerate the Transition Toward Bio‐Based Emulsion Polymers

open access: yesAdvanced Intelligent Discovery, EarlyView.
A machine learning framework simultaneously predicts four critical properties of monomers for emulsion polymerization: propagation rate constant, reactivity ratios, glass transition temperature, and water solubility. These tools can be used to systematically identify viable bio‐based monomer pairs as replacements for conventional formulations, with ...

Impact of inadequate column performance and repair techniques on the seismic performance of RC buildings

open access: yesDiscover Civil Engineering
Nepal lies in a seismically active zone, and recent earthquakes, such as the Gorkha (2015) and Jajarkot (2023) earthquakes, have caused the failure of many reinforced concrete (RC) frame structures.

Post-fire rehabilitation of reinforced concrete columns: effectiveness of ferrocement jacketing under different cooling regimes

open access: yesJournal of Engineering and Applied Science
Fire exposure severely reduces the strength of reinforced concrete (RC) columns, with residual performance strongly influenced by cooling regimes. This study examined 27 columns subjected to 150–600 °C, cooled in air or water, and retrofitted with ...

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

EXPERIMENTAL ASSESSMENT OF CARBON FIBER JACKETING OF STEEL PLATES

open access: yesProceedings of the 6th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2017
It is presented a numerical assessment of experimental data concerning Mode–II delamination tests of steel plates jacketed with Carbon fiber textile sheets. In particular, an inverse identification procedure, based on finite element analysis, has been performed in order to estimate the constitutive parameters of the interface bonding steel and textile.

Scaling of Planar Sodium‐Nickel Chloride Battery Cells to 90 cm2 Active Area

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Large planar Na β′′ alumina electrolytes are prepared by tape‐casting and die‐pressing. These ceramic electrolytes are used to prepare planar sodium‐nickel chloride cells with 90 cm2 active area, providing a high capacity of 7 Ah. Successful cell cycling is demonstrated at 300 °C at rates up to C/4 (20 mA cm−2) for a cumulative capacity of 3.6 Ah cm−2.
