A new smooth failure criterion for concrete inspired by Lubliner's condition

Structural Concrete, EarlyView.
Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

Experimental investigation of evolving anisotropy in unsaturated soils [PDF]

, 2017
This paper investigates the ‘initial’ and ‘evolving’ mechanical anisotropy of a compacted unsaturated soil. Awide campaign of triaxial compression and extension tests, involving different stress and suction paths, has been performed on both ...

Behavior of Long‐Slotted Perforated Steel Plate Fuses in Timber Brace End Connections

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1247-1269, May 2026.
ABSTRACT Steel perforated plate fuses have emerged as a promising solution for mass timber seismic force‐resisting systems, offering tunable energy dissipation mechanisms, such as flexural and shear yielding, through geometric adjustments. This study examines the cyclic performance of perforated steel plate fuses employed in timber braced frames, with ...

Development of experimental concepts for investigating the strength behavior of fine-grained cohesive soil in the Spacelab/space shuttle zero-g environment [PDF]

Three different sets of tests are proposed for the NASA Spacelab experimental program. The first of tests, designed to measure the true cohesion of several different soils, would be carried out in space through use of a specially prepared direct shear ...

Vertical‐Component Seismic Response and System Identification of a 52‐Story High‐Rise Building Using Earthquake Data

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This study investigates the vertical dynamic response of a 52‐story high‐rise building in downtown Los Angeles using small‐magnitude earthquake data recorded by the Community Seismic Network. While seismic design traditionally emphasizes horizontal ground motion, vertical accelerations can have a significant impact on tall structures, leading to ...

High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...
