Seismic Performance Evaluation of Multistory Reinforced Concrete Moment Resisting Frame Structure with Shear Walls
TL;DR: In this article, the authors evaluated the seismic performance of a twelve-story reinforced concrete moment-resisting frame structure with shear walls using 3D finite element models according to such seismic design regulations as Federal Emergency Management Agency (FEMA) guideline and seismic building codes including Los Angeles Tall Building Structural Design Council (LATBSDC) code.
Journal ArticleDOI
Identification of an equivalent viscous damping function depending on engineering demand parameters
TL;DR: In this article, an evolving equivalent viscous damping ratio for a simply supported reinforced concrete beam is estimated for a reinforced concrete structure in the scope of a moderate seismicity context for which steel yielding is not expected.

Dissipations in reinforced concrete components: Static and dynamic experimental identification strategy
TL;DR: The IDEFIX experimental campaign (French acronym for Identification of damping/dissipations in RC structural elements ) has been carried out on RC beams set up on the Azalee shaking table of the TAMARIS experimental facility operated by the French Alternative Energies and Atomic Energy Commission (CEA).

Parameter identification in a probabilistic setting
Bojana Rosić,Bojana Rosić,Anna Kučerová,Jan Sýkora,Oliver Pajonk,Alexander Litvinenko,Hermann G. Matthies +6 more
TL;DR: A computational procedure without any sampling is introduced which works completely deterministically, and is fast and reliable, and some examples have highly nonlinear and non-smooth behaviour and use non-Gaussian measures.
Journal ArticleDOI
Initial versus tangent stiffness-based Rayleigh damping in inelastic time history seismic analyses
TL;DR: In this article, a comprehensive comparison of these two types of Rayleigh damping models is provided, so that a practitioner can objectively choose the type of damping model that best fits her/his needs and is provided with useful analytical tools to design a Rayleigh model with good control on the damping ratios throughout inelastic analysis.

Efficient approaches to finite element analysis in earthquake engineering
TL;DR: In this paper, the authors deal with the modeling of reinforced concrete structures subjected to earthquake ground motion by using simplified multifiber beam element describing the response of structural components and on macro-element accounting for soil-structure interaction.
