Elastic and inelastic multi-storey buildings under earthquake excitation with the effect of pounding
PublicationW artykule przeprowadzono analizę różnic w liniowym i nieliniowym zachowaniu się budynków wielokondygnacyjnych podczas trzęsień ziemi z uwzględnieniem efektu zderzeń pomiędzy nimi. Analizę numeryczną przeprowadzono dla różnych wartości ekstremalnych przyspieszeń gruntu. Wyniki pokazują, iż zaimplementowanie nieliniowego modelu zachowania się budowli jest bardzo istotne w celu uzyskania dokładnej odpowiedzi konstrukcji.

Nonlinear numerical simulation of earthquake-induced pounding between timber frame buildings
PublicationEarthquakes may induce serious dynamic loads acting on buildings, which can lead to damage or even destruction of the whole structure. In densely populated areas, it is quite common that buildings are located very close one to another which can result in pounding between them during ground motions. Due to the environmental awareness, multi-story timber frame buildings are gaining popularity and therefore there is a need to investigate...

Measures of Functional Reliability of Two-Lane Highways
PublicationRural two-lane highways are the most common road type both in Poland and globally. In terms of kilometres, their length is by far greater than that of motorways and expressways. They are roads of one carriageway for each direction, which makes the overtaking of slower vehicles possible only when there is a gap in the stream of traffic moving from the opposite direction. Motorways and express roads are dual carriageways that are...
