In the twenty-first century, the seismic design of buildings seems to have become a fully recognised topic. There are guidelines and standards which should be taken into account by designers in seismic areas. Designers using modern international guidelines have ascertained that the behaviour of structures is not as expected. This may be the result of not taking into account the duration of the shock. The duration of surface vibrations could be one of the basic reasons why some buildings collapse or suffer severe damage to bearing systems as a result of long-duration earthquakes despite being properly designed in accordance with current understanding. Another primary reason for such collapse or damage is that some buildings in seismic areas have irregular structural systems that are sensitive to torsional vibrations. In this paper, a five-storey, irregular-shaped RC building model was subjected to different types of excitations: mining tremors, short-duration earthquakes, long-duration earthquakes. The first stage was a modal analysis based on in situ measurement. After model verification using in situ measurements, the building was then subjected to the three forms of excitation. Numerical studies were performed using a verified FEA model of the building in the time domain. The results of the calculations prove that the duration of the intensive phase of extortion is one of the reasons for the lack of building collapse in mining areas. In cases of mining shocks with a short duration of surface vibration, damage to buildings may occur which does not threaten the safety of their construction. Building collapses occur with earthquakes which are characterised by a much longer duration of the intensive phase of excitation compared to mining shocks. The results of in situ observations of RC structures that have survived a history of mining shocks of varied intensities confirm the results of numerical analyses.

“…In highrise buildings located in the urban areas of many countries, wind-induced vibrations could have a significant influence on the structures [10]. In the Silesian region of Poland, mining excitation also occurs [20]. Irrespective of the source of excitation, vibrations in buildings could be annoying for residents.…”

new Polish guidelines regarding human exposure to vibrations in buildings nowe polskie wytyczne dotyczące narażenia ludzi na wibracje w budynkach Abstract following global trends, Polish regulations on human exposure to vibration in buildings were changed and new Polish guidelines were published in June 2017. In accordance with international trends, two methods of assessment have been added to the regulations: basic rms method and ad-ditional vDv method. for more clarity of rms method, the human vibration perceptivity ratio (hvPr) was introduced to new Polish regulations. In the appendix to the Polish standard, the vi-bration dose value (vDv) method is presented. The third important change in the new version of the Polish standard is measurement equipment that should be used for human perception evaluation. new regulations have precisely described what kind of equipment should be used for low-frequency recording and a new measurement disc for the human perception of vibration on floors has been introduced to the Polish standard. StreszczeniePodążając za światowymi trendami, polskie przepisy dotyczące narażenia ludzi na wibracje w budynkach zostały zmienione, a nowe polskie wytyczne zostały opublikowane w czerwcu 2017 r. Zgodnie z międzynarodowymi trendami w przepisach ujęto dwie metody ewaluacji: podstawową metodę rms i dodatkową metodę vDv. Dla większej przejrzystości metody rms do nowych polskich przepisów wprowadzono Wskaźnik Odczuwalności Drgań przez ludzi (WODl). W załączniku do polskiej normy przedstawiono metodę dawki drgań (vDv). Trzecią ważną zmianą w nowej wersji polskiej normy jest sprzęt pomiarowy, który należy wykorzystać w pomiarach oceny odczuwalności drgań człowieka. nowe przepisy precyzyjnie opisały, jakiego rodzaju sprzęt powinien być używany do rejestracji niskich częstotliwości, do polskiej normy wprowadzono także nowy dysk pomiarowy służący do pomiaru wpływu drgań na ludzi w budynkach.Słowa kluczowe: narażenie ludzi na drgania, przepisy normowe, metoda RMS, VDV, pomiary

“…The studies of damages of civil engineering structures caused by seismic as well as paraseismic loading have revealed that the protection of these structures turned out to be a problematic technical task [4]. Especially for footbridges erected on seismic activity areas, the dynamic loading caused by an earthquake occurs one of the most destructive issues [3].…”

In this paper, the investigation of the dynamic response of a cable-stayed footbridge with steel reinforced concrete deck to foreshocks, a mainshock and an aftershock seismic sequence is delivered. For the aim of the study the finite element (FE) model was prepared with the ABAQUS/Standard software program. The representative seismic events with three components were taken into account in the numerical simulation. For the evaluation of seismic-induced damages in reinforced concrete deck of the footbridge, the concrete damage plasticity (CDP) model was applied.
