A Study on the Effects of Punch-to-Span Ratio and Longitudinal Reinforcement Eigenvalues on the Bearing Capacity of RC Slab–Column Connections

open access: yesBuildings
The region of the RC slab–column connection is subject to complex forces and is susceptible to localized damage, leading to progressive collapse incidents, which has raised considerable concern among the engineering community. At present, the research on

Enabling Under Ice Glider Operations: A Backseat Driver Approach

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

Robustness of Reinforced Concrete Slab Structures: Lessons Learned from Two Full-Scale Tests

open access: yesBuildings
Within the research project ITSAFE, two full-scale structures were built, one consisting of a single-storey, two-span, 7.00 × 14.00 m2 RC frame with a solid slab and another consisting of a two-storey, 7.00 × 7.00 m2 RC frame with solid slabs. In the two-

The Very Highly Ionized Broad Absorption Line System of the QSO SBS1542+541 [PDF]

open access: yes, 1998
We have analyzed the broad absorption line system of the bright (V=16.5) high-redshift (z=2.361) QSO SBS1542+541 using UV spectra from the HST FOS along with optical data from the MMT and the Steward Observatory 2.3m telescope.

Mechanistic Insight Into Ionizable Cationic Lipid‐Mediated Endosomal Escape via Transient Lipid Complexes

open access: yesSmall, EarlyView.
Coarse‐grained simulations show that the formation of transient anionic–cationic lipid pairs regulates the rate‐limiting step for the lamellar‐to‐hexagonal phase transition in mixtures of anionic and cationic lipids mimicking the endosomal membrane after fusion with lipid‐based nanoparticles, thus playing an important role in the endosomal escape of ...

Seismatic design of slab-column connections

open access: yes, 1993
Both experimental and theoretical studies are carried out to investigate the behaviour of concrete flat plates subjected to shear and reversed cyclic moment at their connections. Tests of seven full-size interior slab-column connections subjected to shear and cyclic horizontal load are reported. Based on the test results in this study and previous test

Hole Polaronic Confinement in (111) Yttria‐Stabilised Zirconia

open access: yesSmall, EarlyView.
Ultrathin epitaxial YSZ(111) films unexpectedly develop p‐type mixed conduction and amplified electromechanical coupling under oxidizing conditions. Combined transport measurements and first‐principles modeling reveal that nanoscale confinement and ordered dopant–vacancy complexes stabilize localized O 2p hole polarons at the surface. A canonical ionic

Standardisation of partial strength connections of extended end-plate connections for trapezoid web profiled steel sections [PDF]

open access: yes, 2008
Traditionally, connections are usually classified as pinned or rigid although the actual behaviour is known to fall between these two extreme cases. The use of partial strength or semi-rigid connections has been encouraged by codes and studies on the ...

Influence of Hydrogen Fuel Mixtures on the Oxide Scale Formation of Low‐Carbon Steels in Reheating Furnace Conditions

open access: yessteel research international, EarlyView.
This work illustrates how substituting natural gas with hydrogen as fuel in the reheating furnace will influence the oxide scale formation on the steel surface. Thermogravimetric analysis and characterization techniques are used to investigate oxidation behavior and the formation of oxide phases.
