This research investigates the analysis of reinforced concrete beams subjected to combined axial load, bending moment and shear force. Cross-sections of general shape are divided, along the height, into plane elements. The biaxial behavior is represented according to the smeared rotating crack approach. Using traditionally accepted hypotheses...

This research investigates the simultaneous effect of in-plane and transverse loads in reinforced concrete shells. The infinitesimal shell element is divided into layers with triaxial behavior that are analyzed according to the smeared rotating crack approach. The transverse shear strength of shell elements is associated to an "equivalent"...

In this paper, a model of one-directional propagation of three-component seismic waves in a nonlinear multilayered soil profile is coupled with a multi-story multi-span frame model to consider, in a simple way, the soil-structure interaction modelled in a finite element scheme. Modeling the three-component wave propagation enables the effects...

The seismic response of surficial multilayered soils to strong earthquakes is analyzed through a nonlinear one-directional three-component (1D-3C) wave propagation model. The three components (3C-polarization) of the incident wave are simultaneously propagated into a horizontal multilayered soil. A 3D nonlinear constitutive relation for dry...

The 1DT-3C approach is proposed for bridge modeling, taking into account the spatial variability of the incident seismic motion directly, in the integration of the dynamic equilibrium equation of the soil-bridge system, considering site effects and soil-structure interaction. The proposed modeling technique ensures a considerable gain in...

L'approche 1DT-3C est proposée pour modéliser un pont en tenant compte de la variabilité spatiale du mouvement sismique incident directement dans l'intégration de l'équation de l'équilibre dynamique du système sol-pont, en considérant les effets de site et l'interaction sol-structure. La technique de modélisation proposée assure un gain...

Local wave amplification due to strong seismic motions in surficial multilayered soil is influenced by several parameters such as the wavefield polarization and the dynamic properties and impedance contrast between soil layers. The present research aims at investigating seismic motion amplification in the 2011 Tohoku earthquake through a...

Seismic waves due to strong earthquakes propagating in surficial soil layers may both reduce soil stiffness and increase the energy dissipation into the soil. To investigate seismic wave amplification in such cases, past studies have been devoted to one-directional shear wave propagation in a soil column (1D-propagation) considering one motion...

We propose a one-directional three-component (1D-3C) approach to model the unidirectional (1D) propagation of a three component (3C) earthquake for seismic response analyses of horizontal multilayer soils, considering a 3D nonlinear constitutive behaviour for soils. An elasto-plastic cyclic constitutive behaviour of the Masing-Prandtl-Iwan...

The influence of pore water pressure has to be taken into account when the propagation ofseismic waves in saturated soils is simulated, because it controls the strength decrease during thedynamic process and can induce phenomena such as cyclic mobility and liquefaction. Thedecrease of effective stresses leads to permanent deformation in the...
