Abstract

Ovaj rad istražuje uporabu dronova u procjeni potresne otpornos􀆟 postojećih građevina. Nakon potresa 2020. godine na području Zagreba i Siska, postaje ključno razvi􀆟 sigurnije i učinkovi􀆟je metode prikupljanja podataka o građevinskim objek􀆟ma. Primjena dronova, u kombinaciji s naprednim sustavima za obradu podataka, omogućuje daljinsku procjenu građevina. Značajna prednost primjene osobito je izražena prilikom procjene teško dostupnih dijelova, poput krovova i dimnjaka, čime se izbjegava izlaganje inženjera opasnim situacijama i ubrzava proces. U radu je napravljen kri􀆟čki osvrt na izazove s kojima se suočava primjena dronova te je predložena daljnja op􀆟mizacija ovih metoda za budućnost. U drugom dijelu rada napravljena je studija slučaja u kojoj je prikazana prak􀆟čna primjena nekih od metoda. Za snimanje i analizu 11 odabranih građevina korišten je dron opremljen RGB kamerom i LIDAR senzorom, pri čemu su dobiveni podaci obrađeni posebnim so􀅌verskim ala􀆟ma. Također je napravljena makroseizmička analiza kako bi se utvrdila oštetljivost analiziranih građevina na potres. Rezulta􀆟 rada pokazuju kako dronovi značajno pridonose procjeni potresnog rizika, omogućujući brži i sigurniji pristup, osobito u urbanim sredinama.

Abstract (english)

This paper explores the use of drones in assessing the seismic resistance of exis􀆟ng buildings. A􀅌er the 2020 earthquakes in the Zagreb and Sisak regions, it became crucial to develop safer and more efficient methods for collec􀆟ng data on buildings. The use of drones, combined with advanced data processing systems, enables remote assessment of structures. The significant advantage of this approach is par􀆟cularly evident when evalua􀆟ng hard-to-reach areas, such as roofs and chimneys, reducing the risk to engineers and accelera􀆟ng the process. The paper provides a cri􀆟cal review of the challenges associated with drone applica􀆟on and proposes further op􀆟miza􀆟on of these methods. In the second part of the paper, a case study is presented to demonstrate the prac􀆟cal applica􀆟on of some of these methods. A drone equipped with an RGB camera and a LIDAR sensor was used to capture and analyze 11 selected buildings, with the data processed using specialized so􀅌ware tools. A macroseismic analysis was also conducted to assess the vulnerability of the analyzed buildings to earthquakes. The results show that drones significantly contribute to seismic risk assessment, providing faster and safer access, especially in urban areas.
