TL;DR: In this paper, an enhanced modal analysis technique (Frequency Domain Decomposition) was used to process ambient vibration recordings taken at the Grenoble City Hall building (France), which can contribute to the understanding of the seismic building response and the good relevancy of a modal model based on ambient vibrations for estimating the structural deformation under moderate earthquakes.

TL;DR: In this paper, the authors investigated solutions for an enhanced multifiber beam element accounting for shear and torsion by using higher order interpolations functions to avoid any shear locking phenomena and extended the cross section warping kinematics to non-linear behavior using advanced constitutive laws.

TL;DR: In this paper, a continuous damage model and different simplified numerical strategies are proposed to simulate the behaviour of reinforced concrete (R/C) walls subjected to earthquake ground motions, for 2D modelling of R/C walls controlled primarily by bending, an Euler multilayered beam element is adopted.

TL;DR: In this paper, a novel macroelement for single vertical piles in sand developed within the hypoplasticity theory is presented, where the incremental nonlinear constitutive equations are defined in terms of generalized forces, displacements and rotations.

TL;DR: In this article, a non-linear interface element is presented to compute soil-structure interaction (SSI) based on the macro-element concept, which is appropriate for modelling the cyclic or dynamic response of structures subjected to seismic action.
