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.

abstract Rocking and vertical and horizontal translations of typical “free-field” seismometer installations lead to magnification of the ground motion record. This magnification can be significant for the higher frequency components if the terrain has a relatively low shear-wave velocity. Seismometers placed on foundations which cover a significant part of a wavelength of a horizontally incident wave, experience an attenuated ground motion. A method of correcting the seismograms for these effects is given. Compliance functions for a rigid sphere in a full elastic space are derived and are used to show that, in practical cases, down-hole seismometer installations are not significantly affected by interaction. These compliance functions should be useful in discussing the soil structure interaction of structures erected on bulbous piles. They may be also used as the basis of a method of determining elastic constants of ground at depth, in situ, and at different frequencies.

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.
