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 ...

Triaxial Compression Performance Research of Steel Slag Concrete on the Unified Strength Theory

Applied Sciences, 2020
To better explore the mechanical properties of steel slag concrete (SSC) under triaxial compression, true triaxial tests were performed on SSC with three replacement ratios (30%, 70%, 100%) by a servo-controlled setup (TAWZ-5000/3000).

The Next Generation Virgo Cluster Survey. VII. The intrinsic shapes of low-luminosity galaxies in the core of the Virgo cluster, and a comparison with the Local Group

, 2016
(Abridged) We investigate the intrinsic shapes of low-luminosity galaxies in the central 300 kpc of the Virgo cluster using deep imaging obtained as part of the NGVS. We build a sample of nearly 300 red-sequence cluster members in the yet unexplored $-14

Searching for Machos (and other Dark Matter Candidates) in a Simulated Galaxy [PDF]

, 1997
We conduct gravitational microlensing experiments in a galaxy taken from a cosmological N-body simulation. Hypothetical observers measure the optical depth and event rate toward hypothetical LMCs and compare their results with model predictions. Since we

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 ...

Modified true triaxial Hoek-Brown criterion considering intermediate principal stress effect

Meitan kexue jishu
In order to improve the Hoek-Brown strength criterion not considering the influence of intermediate principal stress on rock strength, the evolutions of rock strength were investigated according to the results of the rock true triaxial compression test ...

Computational Investigation on the Combined Effect of Applied Strain and Pore Configuration on Strain Concentrators in Additively Manufactured Metals

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1656-1679, May 2026.
ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...

Disc galaxies with multiple triaxial structures. II. JHK surface photometry and numerical simulations

, 1996
We present detailed JHK surface photometry with ellipse fits of 13 galaxies selected from previous optical observations as likely candidates for having a secondary bar or a triaxial bulge within the primary bar.

AI‐Enhanced Vibrational Capsule for Minimally Invasive Detection of Abnormal Bowel Tissue

Advanced Science, Volume 13, Issue 23, 23 April 2026.
A fully integrated vibration‐assisted capsule is presented for the minimally invasive detection of bowel lesions. The capsule incorporates a wireless sensor and an eccentric motor to probe tissue mechanics in situ. By coupling triaxial vibration signals with AI‐based classification and analytical modeling, the system enables early, non‐visual ...
