DYNAMIC ANALYSIS OF SOIL-STRUCTURE INTERACTION BY THE THIN LAYERED ELEMENT METHOD

Analysis and design of structures subjected to arbitrary dynamic loadings especially earthquakes have been studied during past decades. In practice, the effects of soil-structure interaction on the dynamic response of structures are usually neglected. In this study, the effect of soil-structure interaction on the dynamic response of structures has been examined. The substructure method using dynamic stiffness of soil is used to analyze soil-structure system. A coupled model based on finite element method and scaled boundary finite element method is applied. Finite element method is used to analyze the structure, and scaled boundary finite element method is applied in the analysis of unbounded soil region. Due to analytical solution in the radial direction, the radiation condition is satisfied exactly. The material behavior of soil and structure is assumed to be linear. The soil region is considered as a homogeneous half-space. The analysis is performed in time domain. A computer program is prepared to analyze the soil-structure system. Comparing the results with those in literature shows the exactness and competency of the proposed method.

Two Alternatives

This paper deals with static and dynamic analysis of asymmetric high-rise building. Two alternatives have been analysed – without dilatation and with dilatation. Then, the influence of the dilatation was discussed. The building was located in 4th seismic area in Slovakia (Bratislava). The description of the building, applied load, considered soil-structure interaction, created calculating models, used analysis and obtained results are mentioned here. The conclusions and the photos of defective repairs of real structures are depicted at the end of the paper.

Zusammenfassung In diesem Beitrag wird eine einfache Modellierungsstrategie zur schnellen und effizienten Berechnung der dynamischen Antwort von Brücken zufolge der Überfahrt mit Hochgeschwindigkeitszügen vorgestellt. Dabei wird sowohl die Boden-Bauwerk-Interaktion als auch die Wirkung des Zuges während der Zufahrphase auf das Tragwerk beziehungsweise nach dem Abfahren berücksichtigt. Im mechanischen Modell wird die Brücke als Bernoulli-Euler -Balken, welcher von den statischen Achslasten des Hochgeschwindigkeitszugs überfahren wird, beschrieben. Feder und Dämpfer an den Rändern des Balkens bilden das Verhalten des Untergrunds ab. Die Ergebnisse eines Anwendungsbeispiels zeigen, dass die Boden-Bauwerk-Interaktion die berechnete dynamische Antwort wesentlich beeinflusst.
