A numerical investigation on the fire response of a steel girder bridge

Paya-Zaforteza, I.; Garlock, Maria E.M. (Elsevier, 2012-08)

The response of bridges subject to fire is an under researched topic despite the number of bridge failures caused by fire. Since available data shows that steel girder bridges are especially vulnerable to fire, this paper ...
Damping Perturbation Based Time Integration Asymptotic Method for Structural Dynamics

Lázaro, Mario (World Scientific, 2022-12)

[EN] In this paper a novel time integration numerical method based on artificial perturbation of damping is proposed. Viscous dissipative terms in the structural dynamics equations of motion are perturbed by an artificial ...
Dynamic train-track interaction at high vehicle speeds-Modelling of wheelset dynamics and wheel rotation

Torstensson, P. T.; Nielsen, J. C. O.; Baeza González, Luis Miguel (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)

[EN] Vertical dynamic traintrack interaction at high vehicle speeds is investigated in a frequency range from about 20 Hz to 2.5 kHz. The inertial effects due to wheel rotation are accounted for in the vehicle model by ...
Key aspects in the analysis and design of Hyperloop(TM) infrastructure under static, dynamic and thermal loads

Museros Romero, Pedro; Lazaro, Carlos; Pinazo, Benjamín; Monleón Cremades, Salvador (Elsevier, 2021-07-15)

[EN] Hyperloop is an avant-garde idea for high-speed transportation of passengers and freight in a \emph{pod} or capsule-like vehicle travelling through an hermetically sealed tube with reduced internal pressure. Its maximum ...
Numerical Evaluation of the Vibration Reduction Index for Structural Joints

Ramis Soriano, Jaime; Segovia, Enrique; Alba Fernández, Jesús; Carbajo San Martín, Jesús; Godinho, Luis (Polish Scientific Publishers, 2012)

The present paper addresses the analysis of structural vibration transmission in the presence of structural joints. The problem is tackled from a numerical point of view, analyzing some scenarios by using finite element ...
On Total Reuse of Krylov Subspaces for an iterative FETI-solver in multirate integration

Seibold, Andreas; Rixen, Daniel; Fresno Zarza, Javier (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] In this work, we adapt a Total Reuse of Krylov Subspaces for usage in a GMRESsolver and apply it to nonlinear structural-dynamics examples. These examples are then solved by a multirate FETI-method, the nonlinear ...
Prediction of the non-linear aeroelastic behavior of a cantilever flat plate and equivalent 2D model

Gil, A.; Tiseira, Andrés-Omar; Quintero-Igeño, Pedro-Manuel; Cremades-Botella, Andrés (Elsevier, 2021-06)

[EN] Reducing structure weigh is one of the main strategies for decreasing environmental and manufacturing costs of engineering solutions. The reduction in material is normally related with a higher impact of aeroelastic ...
Study of turbocharger shaft motion by means of non-invasive optical techniques: Application to the behaviour analysis in turbocharger lubrication failures

Pastor, José V.; Serrano, J.R.; Dolz, Vicente; López Hidalgo, M.A.; BOUFFAUD, F. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2012)

[EN] This paper presents a novel non-invasive technique to estimate the turbocharger shaft whirl motion. The aim of this article is to present a system for monitoring the shaft motion of a turbocharger, which will be used ...
