Analysis of Tram Traffic-Induced Vibration Influence on Earthquake Damaged Buildings

The Zagreb 2020 earthquake severely damaged the historic centre of city. Most damage occurred on masonry residential buildings, many which are situated very close to tram track. Although traffic-induced vibrations generally do not affect surrounding they can be harmful buildings by a previous earthquake. Vibrations could contribute further propagation existing cracks. effect depends factors, one most important being distance between track and building. highest at source, energy loss occurs due transfer through soil recipients. impact tram-induced earthquake-damaged in city is investigated this paper. analysis conducted tramway network scale identify critical locations performing continuous monitoring risk based from track, vibration amplitude building damage. Further investigation level evaluate influence actual Based detailed signal analysis, characterization performed, evaluated.
