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.

This paper presents a numerical study of soil-structure interaction (SSI) and structure-soil-structure interaction (SSSI) effects on response of twin buildings during earthquake excitations. The buildings are modeled as shear buildings and the soil is simulated by a discrete model representing a visco-elastic half-space subjected to earthquake acceleration. Equation of motion of twin buildings with different conditions, fixed based (FB), SSI and SSSI, are developed via an analytical procedure and solved numerically. Buildings responses are evaluated for aforementioned three conditions considering various soil types and compared together. One must say that soil causes change in distribution of responses throughout the buildings while ignoring soil interaction may lead to detrimental effects on buildings. Anyway, interaction between twin buildings with SSSI condition slightly mitigates soil unfavorable effects compare to one building with SSI condition. In addition, it is found that influence of soil is very significant for soft to stiff soils whereas negligible for hard soils.
