Abstract

Potresno djelovanje predstavlja gorući problem prilikom projektiranja konstrukcija u Republici Hrvatskoj. Potresna izolacija nudi učinkovito rješenje smanjenja potresnih učinaka i posljedica na građevinu. Glavni cilj potresne izolacije je odvajanje konstrukcije od horizontalnih komponenti gibanja tla umetanjem potresnih izolatora. Potresni izolatori su konstrukcijski elementi s malom horizontalnom krutošću koji doprinose produljenju osnovnog perioda titranja konstrukcije. U radu su opisane osnovne vrste potresnih izolatora i načini njihove ugradnje. Napravljena je usporedba modela konstrukcije sa i bez potresne izolacije u programskom paketu ETABS 20. Analizirana je armiranobetonska okvirna konstrukcija potresno izolirana kombinacijom elastomernih ležajeva s visokim prigušenjem i lončastih ležajeva.

Abstract (english)

Seismic action is a pressing problem in structural design in Croatia. Seismic isolation provides an effective solution to reduce seismic impacts and consequences on the building. The main objective of seismic isolation is to decouple the structure from the horizontal components of ground motion by inserting seismic isolators. Isolators are structural elements with low horizontal stiffness that contribute to lengthening the fundamental period of vibration of the structure. The paper describes the basic types of seismic isolators and their installation methods. A comparison of the construction model with and without seismic isolation was carried out using the ETABS 20 software package. A reinforced concrete frame structure that was seismically isolated with a combination of high damping rubber bearings and pot bearings was analysed.
