Dynamic Test of Negative Stiffness Damped Outrigger With Damping Amplification

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 4, Page 1141-1155, 10 April 2025.
ABSTRACT This paper proposed a novel negative stiffness damped outrigger with damping amplification (NSDO‐DA) through a smart combination of an L‐shape lever, a precompressed disc spring brace (DSB), and a viscous damper. A theoretical model of the NSDO‐DA considering nonlinear adaptive negative stiffness, damping amplification of nonlinear viscous ...

Comparison of field and laboratory models of the load bearing capacity in coffee plantations Comparação de modelos de capacidade de suporte de carga do solo de campo e laboratório em plantações de café

Ciência e Agrotecnologia, 2013
Precompression stress is an important property for assessment of tropical soil structure sustainability and is often determined in laboratory tests. The objective of this study was to compare the load bearing capacity models obtained with controlled ...

Momentum and energy propagation in tapered granular chains

, 2013
We study momentum and energy propagation in 1D tapered chains of spherical granules which interact according to a Hertz potential. In this work we apply the binary collision approximation, which is based on the assumption that transfer of energy along ...

Dynamics of periodic mechanical structures containing bistable elastic elements: From elastic to solitary wave propagation [PDF]

, 2014
We investigate the nonlinear dynamics of a periodic chain of bistable elements consisting of masses connected by elastic springs whose constraint arrangement gives rise to a large-deformation snap-through instability.

Simulation of Autogenous Self‐Healing in Lime‐Based Mortars

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 1, Page 359-375, January 2025.
ABSTRACT Throughout history, architectural heritage has been constructed using masonry, clay or stone elements, and lime‐based mortars. Over time, old buildings are subjected to different degrees of movement and degradation, leading to the formation of microcracks.

Wave Propagation in a Strongly Nonlinear Locally Resonant Granular Crystal

, 2017
In this work, we study the wave propagation in a recently proposed acoustic structure, the locally resonant granular crystal. This structure is composed of a one-dimensional granular crystal of hollow spherical particles in contact, containing linear ...

Critical current measurement with spatial periodic bending imposed by electromagnetic force on a standard test barrel with slots\ud [PDF]

, 2006
We have developed and validated a straightforward and fast method to investigate the response of technological superconducting strain sensitive wires (e.g., Nb3Sn) to a spatial periodic bending strain. In the present concept of cabled superconductors for

Performance Analysis of Self‐Resetting Pier–Beam Node of Sheet–Pile Bridge Based on Vehicle–Bridge Coupling Vibration

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
To address the issue of excessive stress at the secondary pier–beam joints of multispan continuous sheet–pile bridges caused by large longitudinal displacements, this study proposes a novel structural configuration incorporating prestressed self‐resetting reinforcement at the pier–beam connection.
