Abstract

U diplomskom radu obranjena je tema „Suvremeni pristupi proračunu potresnog djelovanja na AB konstrukcije“. U prvom dijelu rada tema je obranjena kroz teoriju koja je zatim primijenjena u numeričkom modelu konstrukcije gdje je izvršen statički i dinamički proračun konstrukcije te dimenzioniranje. Teorija je detaljno obrađena uz odgovarajuće skice, grafičke priloge i ključne jednadžbe koje su važne u dinamici konstrukcija. Prikazana je osnovna problematika potresa, njegova pojava i posljedice, osnovni pojmovi dinamike konstrukcija te su detaljno prikazane metode proračuna potresnog djelovanja.. Objašnjene su prednosti i mane pojedinih metoda proračuna potresa. U poglavlju „Energetski pristupi“ govori se o energetskom pristupu proračuna konstrukcija. To je jedan od novijih pristupa koji se zasniva na utrošenoj energiji konstrukcije pri potresu. U četvrtom poglavlju prikazane su razli ite vrste nosivih sustava, utjecaj duktilnosti i faktora ponašanja te na ini armiranja. Napravljen je numeri ki model konstrukcije u programu SCIA Engineer 18 radi usporedbe rezultata. Uspoređene su metode bočnih sla i modalna analiza te je s mjerodavnim rezultatima dimenzionirana konstrukcija. Doprinos rada je u komparativnoj analizi rezultata dobivenih različitim metodama.

Abstract (english)

In the Master's Thesis, topic „Innovative approaches for a seismic design of reinforced concrete structures“ was discussed. In the first part of the assignment, topic was elaborated throughout a theory and then it was applied in numerical model of structure where static and dynamic design was performed. The theory was elaborated in detail with appropriate sketches, graphical inset and equations that are important in dynamics of structures. Basic problems of an earthquake, its occurrence and consequences with structural dynamics details of seismic analysis methods such as ELF method, modal analysis, pushover analysis and dynamic nonlinear analysis were discussed. The part „Energy – based design“ discusses the energy approach of structural calculation. It is one of the most recent approaches, based on the energy Consule by an earthquake. In the fourth part, different types of structural systems, the influence of ductility and behaviour factor and reinforcement are presented. A numerical design model was created in SCIA Engineer 18 to compare the results. The lateral force methods and the modal analysis were compared and the structure was designed with the relevant results. The contribution of the thesis is in the comparative analysis of the results obtained by different seismic methods.
