Damage identification on spatial Timoshenko arches by means of genetic algorithms
, 2017 In this paper a procedure for the dynamic identification of damage in spatial Timoshenko arches is presented. The proposed approach is based on the calculation of an arbitrary number of exact eigen-properties of a damaged spatial arch by means of the ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Fiber‐based beam‐column elements featuring an effective material constitutive law with softening can capture the degrading response of structural members under extreme loading. However, these elements exhibit strain localization and mesh divergence, which impedes their accuracy.

Uncertainty Quantification in Modeling of Steel Structures using Timoshenko Beam [PDF]
Journal of Structural and Construction Engineering, 2019 This paper quantifies the uncertainty emanated from modeling steel structures using a Timoshenko beam. Using continuous beams to model building structures is a conventional approach in structural dynamic analyses.

On the Controllability of a Slowly Rotating Timoshenko Beam
Zeitschrift für Analysis und ihre Anwendungen, 1999 We consider a slowly rotating Timoshenko beam in a horizontal plane whose move-ment is controlled by the angular acceleration of the disk of a driving motor into which the beam is clamped. The problem to be solved is to transfer the beam from a position of rest into a position of rest under a given angle within a given time.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Understanding the dynamic behavior of structural components is crucial for optimizing performance and ensuring structural integrity. This study presents a new method that combines a systematic experimental investigation of four distinct hole geometries (circular, square, compact rectangular, and long rectangular) with varying hole counts, all ...

Vibrations of a Timoshenko beam on an inertial foundation under a moving load
MATEC Web of Conferences, 2018 In the paper vibrations of the Timoshenko beam on an inertial foundation subjected to a moving force are discussed. Considered model of the inertial foundation is described by three parameters.

Hygromnemics: Programmable Material Memory Matter Actuators via Wet Pre‐Constraining
Advanced Materials Technologies, Volume 10, Issue 23, December 3, 2025.Humidity‐based pre‐constraining creates hygromnemics‐shape memory matter. From identical biocomposites actuation in dry and wet states is obtained via hygromnemic and hygromorphic actuation, respectively. Hygromnemic actuators present long‐ and short‐term shape memory abilities.
