Issued as a Documentation Report on an Investigation of Field-Made Joints in Prestressed Reinforced Concrete Highway Girder Bridges, Project IHR-303, Phase 2 [PDF]

, 1977
A prototype bridge girder was designed, built, and tested. The 250 ft long two-span girder was made of 3 precast segments about 88, 74, and 88 ft in length. The segments were supported on 3 final and 2 temporary supports.

Correlation of total organic C, particulate and mineral‐associated C fractions with strength indicators in Oxisols

Soil Science Society of America Journal, Volume 89, Issue 5, September/October 2025.
Abstract The specific role of each fraction of soil C (i.e., particulate [POC] or mineral‐associated organic carbon [MAOC]) in each soil strength mechanism remains unexplored. We investigated the relationships of total organic C and its physical fractions with soil strength of two tropical soils (sandy clay loam [SCLsoil] and sandy clay [SCsoil]).

Seismic design and performance evaluation of post‐tensioned CLT shear walls with coupling U‐shaped flexural plates in Canada

Earthquake Spectra, Volume 41, Issue 3, Page 2203-2224, August 2025.
Post‐tensioned cross‐laminated timber (PT‐CLT) walls coupled with U‐shaped flexural plates (UFPs) have proved to be a low‐damage seismic force‐resisting system (SFRS) due to their self‐centering capability and stable energy dissipation. Global efforts have been made to explore the applicability of PT‐CLT walls as primary SFRSs in mass timber buildings.

Influence of the formulation of an alumina powder on compaction [PDF]

, 2009
International audienceThe compression of ceramic powders requires the addition of organic materials to insure tablet cohesion. For the compaction of formulated ceramic powders it is necessary to supply them energy.

Fracturing behaviors of flawed granite induced by dynamic loadings: A study based on DIP and PFC

Deep Underground Science and Engineering, Volume 4, Issue 2, Page 290-304, June 2025.
This research examines granite's mechanical properties under split‐Hopkinson pressure bar testing, focusing on factors such as grain size and flaw dimensions. The study reveals that tension cracks are prevalent across grain sizes, with most intergrain cracks occurring between feldspar and quartz.

Modeling Temperature‐ and Rate‐Dependent Behavior of Soft Soils: A Thermo‐Visco‐Hypoplastic Approach

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 8, Page 2076-2091, 10 June 2025.
ABSTRACT Temperature effects become important in a number of geotechnical applications, such as nuclear waste disposal facilities, buried high‐voltage cables, pavement, energy geostructures and geothermal energy. On the other hand, soft soils act time‐ and strain rate dependent.

Dynamic soil water retention properties: Exploring the interplay of moisture states and soil structure dynamics in a compacted Andosol

Vadose Zone Journal, Volume 24, Issue 3, May/June 2025.
Abstract The influence of soil structure dynamics on spatiotemporal variability in soil water flows and distribution is generally omitted in hydrological modeling across scales. Soils like Andosols exhibit important structural dynamics, which affects the accurate representation of soil water distribution and solute transport.

Spontaneous wettability patterning via creasing instability [PDF]

, 2015
Surfaces with patterned wettability contrast are important in industrial applications such as heat transfer, water collection, and particle separation. Traditional methods of fabricating such surfaces rely on microfabrication technologies, which are only
