Utrditev upogibno obremenjenega armiranobetonskega nosilca s kompozitnimi CFRP lamelami : magistrsko delo = Strengthening of a reinforced concrete girder with a CFRP laminate under bending load : master thesis

Klun, Martin

Magistrsko delo zajema primerjalne analize in dimenzioniranje upogibno obremenjenega, neutrjenega in utrjenega armiranobetonskega nosilca s CFRP lamelo. Za obstoječi armiranobetonski nosilec neznanih ... karakteristik je najprej z uporabo nedestruktivnih in destruktivnih metod prikazana ocena trenutnega stanja, geometrije, lege armaturnih palic in materialnih karakteristik. Določitev le-teh je pomembna za natančnost in uspešnost vseh nadaljnjih analiz in dimenzioniranja utrditvene CFRP lamele. V okviru dela je izveden štiri točkovni upogibni preizkus neutrjenega in utrjenega armiranobetonskega nosilca. Po opravljenem eksperimentu se je izvedlo numerično analizo s programom Abaqus in analitični izračun v skladu s standardom Eurocode ter medsebojna primerjava rezultatov obeh analiz. S primerjavo rezultatov analitičnega izračuna in numerične analize z eksperimentalnimi rezultati je bila ugotovljena natančnost določitve dejanskega obnašanja tako neutrjenega kot tudi utrjenega realnega nosilca s pomočjo analitičnih in numeričnih metod. V zadnjem delu je skladno s standardi in priporočili narejen izračun dimenzioniranja utrjenega armiranobetonskega nosilca s CFRP lamelo v projektnem stanju. Rezultati dimenzioniranega %računskega% stanja utrjenega nosilca so primerjani z rezultati predhodnih analiz dejanskega stanja s čimer se pokaže potrebna varnost pri dimenzioniranju. Na podlagi izpeljanih izrazov za dimenzioniranje in računskih kontrol iz priporočil je narejen preprost program za optimalno dimenzioniranje upogibne utrditve armiranobetonskega nosilca s CFRP lamelo.
