Abstract

Vibracije od tramvajskih vozila mogu predstavljati problem za zgrade oštećene u potresu. U ovom radu prikazan je utjecaj različitih tipova stanja kolosijeka i različitih režima vožnje na zgrade oštećene u potresu. Prilikom potresa oštećen je veliki broj zgrada u centru Zagreba, no provesti samu analizu za sve oštećene zgrade i za sve režime vožnje tramvajskih vozila je poprilično opsežno i zahtjevno. Zbog toga uzeta je jedna lokacija kao ogledna kako bi se na njoj provele vibro-akustičke analize na temelju prijenosnih funkcija. Analizama su dobivene transfer funkcije između tramvajskog kolosijeka i zgrade. Transfer funkcije dobivene su dijeljenjem vibracija od zgrade sa vibracijama od tramvaja. Vibracije od spomenutih režima vožnje i stanja kolosijeka služili su kao ulazni parametar za daljnju analizu vibracija te izradu modela zgrade HŽ infrastrukture. Temeljem analize odgovora konstrukcije doneseni su zaključci o utjecaju vibracija na zgradu.

Abstract (english)

Vibrations from tram vehicles can represent a problem for earthquake-damaged buildings. This paper presents the influence of different types of track conditions and different driving regimes on earthquake-damaged buildings. During the earthquake, a large number of buildings in the center of Zagreb were damaged, but conducting the analysis for all damaged buildings and for all modes of operation of tram vehicles is quite comprehensive and demanding. For this reason, one location was taken as an example in order to carry out vibro-acoustic analyzes based on transfer functions. Transfer functions between the tram track and the building were obtained through analyses. The transfer functions were obtained by dividing the vibrations from the building with the vibrations from the tram. Vibrations from the aforementioned driving regimes and track condition served as an input parameter for further vibration analysis a of the HŽ infrastructure building. Based on the analysis of the structure's response, conclusions were drawn about the impact of vibrations on the building.
