Soil response analysis consistently indicates that the stress–strain relationship of soils is non-linear and shows hysteresis. When focusing on forced response simulations, time integrations based on modal analysis are widely considered; however, parametric analysis, non-linear behavior and complex damping functions make difficult the online use of standard discretization strategies, e.g., those based on the use of finite element. In this paper, we propose a new harmonic analysis formulation, able to address forced response simulation of soils exhibiting their characteristic non-linear behavior. The solution can be evaluated in real-time from the offline construction of a parametric solution to the associated linearized problem within the Proper Generalized Decomposition framework.

Since water, oil or gas pipeline systems are a key part of modern development, therefore, it is important to ensure an appropriate behavior under seismic action. In this paper, the seismic response of buried pipelines is numerically simulated using a three-dimensional (3D) parametric model of soil-pipeline interaction. The role of several parameters on both soil and pipeline are incorporated into a 2D-1D space separated representation based on the Proper Generalized Decomposition (PGD) framework, which allows addressing 3D parametric problems while reducing the computational complexity of 1D and 2D characteristic problems. These results can be used for design, safety evaluation and protection of buried pipelines crossing seismic area and can be calculated in real time from the parametric solution of the associated problem within the PGD framework.

Fuentes: koha, openalex, orcid Acceso abierto — DIAMOND Uno de los problemas más importantes y comúnmente encontrados en la ingeniería sísmica es la evaluación de la respuesta del terreno donde se ubicala edificación. La respuesta dinámica del suelo es un fenómeno sumamente complejo, que depende de un gran número de variables, tanto de las propiedades del mismo suelo como de la excitación a la que se encuentre sometida. El comportamiento no lineal del suelo durante un evento sísmico tiene un papel predominante en el análisis actual de la respuesta del sitio, lo que indica que su relación esfuerzo-deformación es no lineal e histerética, debido a esto, el enfoque lineal debe ser modificado para proporcionar estimaciones razonables de respuesta del terreno para los problemas prácticos de interés. En el presente artículo se muestra la influencia, en el análisis de la respuesta sísmica local de la presa de tierra "Las Dos Bocas", ejercida al considerar distintas excitaciones sísmicas, así como las propiedades dinámicas del suelo en función del nivel de deformación inducido. Demostramos cómo la no linealidad puede afectar la amplificación del suelo en función de diferentes fuentes de excitación. Aquí, el comportamiento no lineal con un enfoque en la respuesta del sitio 1-D se desarrolla aplicando un método iterativo para lograr la aproximación lineal equivalente del suelo, basada en las propiedades no lineales del material.

Fuentes: openalex, orcid, sjr Acceso abierto — GOLD Many models assumed to be able to predict the response of structural systems fail to efficiently accomplish that purpose because of two main reasons. First, some structures in operation undergo localized damage that degrades their mechanical performances. To reflect this local loss of performance, the stiffness matrix associated with the structure should be locally corrected. Second, the nominal model is sometimes too coarse grained for reflecting all structural details, and consequently, the predictions are expected to deviate from the measurements. In that case, there is no small region of the model that needs to be repaired, but the entire domain needs to be repaired; therefore, the entire structure-stiffness matrix should be corrected. In the present work, we propose a methodology for locally correcting or globally enriching the models from collected data, which is, upon its turn, completed beyond the sensor’s location. The proposed techniques consist in the first case of an L1-minimization procedure that, with the support of data, aims at the same time period to detect the damaged zone in the structure and to predict the correct solution. For the global enrichment, instead, the methodology consists of an L2-minimization procedure with the support of measurements. The results obtained showed, for the local problem, a correction up to 90% with respect to the initially incorrectly predicted displacement of the structure, and for the global one, a correction up to 60% was observed (this results concern the problems considered in the present study, but they depend on different factors, such as the number of data used, the geometry or the intensity of the damage). The benefits and potential of such techniques are illustrated on four different problems, showing the large generality and adaptability of the methodology.

When the considered problem involves some parameters aiming at computing its parametric solution the difficulty is twofold. The authors proposed, in some of their former works, strategies for solving both, however they suffer from a deep intrusiveness. This paper proposes a totally novel approach that from any existing discretization is able to reduce the 3D parametric complexity to the one characteristic of a simple 2D calculation. Thus, the 3D complexity is reduced to 2D, the parameters included naturally into the solution, and the procedure applied on a discretization performed with a standard software, which taken together enable real-time engineering.
