Nonlinear features identified by Volterra series for damage detection in a buckled beam
(E D P Sciences, 2014-01-01)
The present paper proposes a new index for damage detection based on nonlinear features extracted from prediction errors computed by multiple convolutions using the discrete-time Volterra series. A reference Volterra model ...
Numerical Study of the Seismic Efficiency of Buckling-Restrained Braces for Near and Far-Fault Inputs
(Bentham Science Publishers, 2015-05)
Buckling-restrained braces are commonly installed in building structures as concentric diagonal or chevron braces to protect the main construction from seismic actions. These elements have shown repeatedly their usefulness ...
On dynamic quasi-bifurcation of simple shell-like systems under impulsive loads
(Universidad de Puerto Rico, 2018-06)
The nonlinear dynamic response and buckling of a simple, two degree of freedom system is investigated in this work under an impulsive load that simulates a nearby detonation-like explosion. The model considered in this ...

Structural Performance of Bridges in the Offshore Maule Earthquake of 27 February 2010
(EARTHQUAKE ENGINEERING RESEARCH INST, 2012)
Of the nearly 12,000 highway bridges in Chile, approximately 300 were damaged in this earthquake, including 20 with collapsed spans. Typical failure modes include damage to connections between super- and substructures, ...
Seismic Design of Multi-story Buildings with Metallic Structural Fuses
(2006-06-28)
Seismic design relies on inelastic deformations through hysteretic behavior. However, this translates into damage on structural elements, permanent system deformations following an earthquake, and possibly high cost for ...
Análise numérica e experimental de flambagem em cilindros de paredes finas
(Universidade Estadual Paulista (Unesp), 2017-08-15)
Estruturas de paredes finas são muito utilizadas na engenharia moderna devido sua boa relação entre peso e resistência. Sua aplicação vai desde obras civis, como cúpulas em edifícios e pontes, até estruturas aeronáuticas ...
Momento fletor resistente à flambagem lateral com torção de vigascelulares de aço em temperatura ambiente e situação de incêndio
(Universidade Federal de Minas GeraisUFMG, 2019-03-07)
This work deals with a numerical study on the structural behavior of steel cellular beams at room temperature, and under fire condition, focused on the lateral-torsional buckling limit state. The main objective is to propose ...
