  abstract  = {In the design of a structure, the implementation of reliable soil-foundation-structure interaction into the analysis process plays a very important role. The paper presents a determination of parameters of a suitably chosen soil-foundation model and their influence on the structure response. Since the mechanical data for the structure can be determined with satisfactory accuracy, the properties of the soil-foundation model were identified using measured dynamic response of the real structure. A simple model describing soil-foundation structure was incorporated into the classical 3-D finite element analysis of the structure with commercial software. Results obtained from the measured data on the pier were afterwards compared with those obtained with the finite model of the pier-foundation-soil structure. On the basis of this comparison the coefficients describing the properties in the soil-foundation model were adjusted until the calculated dynamic response coincided with the measured ones. In this way, the difference between both results was reduced to 1\%. Full-scale tests measuring eigenmotion of the bridge were performed through all erection stages of the new bridge in Maribor. In this way an effective and experimentally verified 3-D model for a complex dynamic analysis of the bridge under the earthquake loading was obtained. The significant advantage of the obtained model is that it was updated on the basis of the dynamic measurements thus improving the model on the basis of in-situ geomechanical measurements. The model is very accurate in describing the upper structure and economical in describing the soil mass thus representing an optimal solution regarding computational efforts.},

  abstract  = {Bei der Gr{\"u}ndung von schweren Bauwerken (z.B. Hochh{\"a}usern auf Gr{\"u}ndungsplatten und pf{\"a}hlen) wird der Lastabtrag in den Baugrund durch eine starke Interaktion zwischen Bauwerk und Baugrund bestimmt. Der Baugrund kann ph{\"a}nomenologisch als Mehrphasenkontinuum beschrieben werden, bei dem die Phasen Feststoff, Fl{\"u}ssigkeit und Gas in mechanische Wechselwirkung treten. Die Wechselwirkung zwischen der Deformation des Feststoffes und der Str{\"o}mung des Porenwassers spielt unter der Lasteinwirkung des Bauwerks und unter dynamischer Erregung eine zentrale Rolle. Bei komplexen Gr{\"u}ndungsverh{\"a}ltnissen k{\"o}nnen die Deformations- und Spannungszust{\"a}nde realit{\"a}tsnah nur durch dreidimensionale Modelle erfasst werden. Je nach Baufortschritt stellen sich die Probleme dabei unterschiedlich dar. Der vorliegende Beitrag besch{\"a}ftigt sich mit der f{\"u}r die mit der Simulation mit der Methode der finiten Elemente notwendigen Modellierung und der rechnergest{\"u}tzten Netzgenerierung f{\"u}r die Baugrund-Tragwerk-Strukturen. Bei komplexen dreidimensionalen Gr{\"u}ndungskonstruktionen ist eine solche rechnergest{\"u}tzte Diskretisierung mit finiten Elementen zweckm{\"a}ßig, die das geotechnische System und dessen Randbedingungen und Lasten umfassend beschreiben und verwalten kann. Daf{\"u}r werden geeignete Software-Werkzeuge vorgestellt, mit denen sich dreidimensionale, zeitabh{\"a}ngige Systeme modellieren und diskretisieren lassen. Die Kontaktproblematik zwischen Baugrund und Tragwerk und die Besonderheiten des Mehrphasenkontinuums stellen besondere Anspr{\"u}che an die Diskretisierung. Zudem werden Methoden vorgestellt, die das akkumulierte Gr{\"u}ndungsmodell, das sich {\"u}ber den Bauablauf ergibt, verwalten und die verschiedenen Bauzust{\"a}nde in einem dynamischen Modell bereitstellen.},

  abstract  = {Thin-walled spatial structures are broadly used in the modern technician and building. In fuel industry for long-term keeping of oil and gas are used reservoirs of various capacity, which on technological reasons can be shipped under the soil. Shells of reservoirs combine in itself high toughness and low specific consumption of materials. At the same time, being under the soil, they feel steady-state and dynamic loads from ambiance, which particularly in the event, when reservoir is empty, can bring about the loss of stability of its form. On the other hand contact interactions of shell and soil greatly depend on features of ambiance and its saturating of liquid. For building generalized porous springy ambiance models, saturated by the liquid, it is possible to use Bio equations of motion for displacement of hard and fluid phases. Elaboration of mathematical specified interaction models and theirs realization by means of modern computing software allows to study behaviour of spatial thin-walled designs on base of geometric nonlinear theory of shells},
