| Popis: | Ovim diplomskim radom obraden je proraˇcun ojaˇcanja te ispitivanje ˇceliˇcnih okvira. Prikazano je nekoliko mogu´cih metoda ojaˇcanja. Prethodnim proraˇcunom koriste´ci numeri ˇcke modele odredeno je oˇcekivano ponaˇsanje svakog od tri okvira. Na osnovu numeri ˇcke analize praznog okvira odredene su dimenzije za dva tipa ojaˇcanja: okvira poduprtog koncentriˇcnim ukrutama te okvira s disipativnim prikljuˇckom TADAS. Nakon izrade ojaˇcanja, prazan okvir te oba ojaˇcana okvira ispitana su cikliˇcki. Rezulati ispitivanja su usporedeni s prethodnim proraˇcunom te su usporedeni rezulati ispitivanja sva tri okvira. In this paper deals with strengthening and testing of steel frames. Serveral methods of strengthening are shown. Using preliminary calculations by numerical modelling behaviour of all three frames is determined. Based on numerical models, design is carried out for two types of strengthening: special concentrically braced frame and frame with dissipative device TADAS. After strengthening fabrication, all three frames are tested under cyclic load. Results of tests are compared to those of numerical models and between three frames. |
