Reconstruction method of masonry buildings with inner core made of cross laminated timber panels

Magistrsko delo prikazuje tehnologijo izvedbe nove metode rekonstrukcije stare potresno neodporne zidane stavbe. V notranjost zidane stavbe smo vstavili novo sekundarno leseno konstrukcijo iz križno lepljenih lesenih masivnih plošč (kot notranje jedro stavbe) in jo ustrezno spojili s staro primarno zidano konstrukcijo. Na tak način smo utrdili prvotno potresno neodporno zidano konstrukcijo z novo leseno konstrukcijo, ki prevzame celotno potresno obremenitev. V delu je na vzorčnem primeru tipične potresno neodporne zidane stavbe predstavljena tehnologija izvedbe konstrukcijskih in sanacijskih ukrepov. Prikazani so detajli izvedbe ter ukrepi, ki so tudi računsko analizirani. Z izračuni smo dokazali možnost utrditve zidane stavbe z ustreznim spajanjem z novim notranjim lesenim jedrom in doprinos izvedenega posega z gradbeno – fizikalnega vidika. Na koncu naloge sledi še ocena stroškov predstavljene metode rekonstrukcije ter primerjava z ocenjenimi stroški ostalih tradicionalnih metod utrditev. In my master's thesis technology of performing a new reconstruction method of an old masonry building with inferior seismic resistance is presented. In the interior of the masonry building new secondary timber construction made of cross laminated solid timber panels (as the inner core of the building) is embedded and adequately connected to the old primary masonry construction. In such a way the primary masonry construction with inferior seismic resistance is retrofitted with the new timber construction which assumes the entire seismic load. In the thesis technology of performing construction and corrective measures on the model of a typical masonry building with inferior seismic resistance is presented. Details of the performance are described and also measures which are analyzed with calculation. The feasibility of strenghtening the masonry building with a suitable conjunction to the new timber inner core and contribution of the performed procedure in the light of construction and physical aspect were substantiated with calculations. In the end of the thesis there is a cost estimate of the presented reconstruction method and a comparison with the estimated costs of other traditional methods of strenghtening.
