ACCURATE AND EFFICIENT MODELING OF THE HYSTERETIC BEHAVIOR OF SLIDING BEARINGS

open access: yesProceedings of the 7th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2019
This paper presents a uniaxial phenomenological model for the simulation of the hysteretic behavior typically exhibited by sliding bearings deforming along one of their transverse directions under the effect of an axial compressive load. The proposed hysteretic model is able to take into account the dependency of the device restoring force on the ...

Seismic Energy Dissipation in Bridges for Performance Enhancement

open access: yesApplied Sciences
Modern performance-based bridge design seeks to control damage in specific failure modes in order to balance safety and economy, particularly in high-seismic regions where inelastic and ductile deformation is expected to occur, both in the structure and ...

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots

open access: yesAdvanced Robotics Research, EarlyView.
Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...
