“…U literaturi su opisane mnoge metode i primjene postupka za ispitivanje okolnih (ambijentalnih) vibracija i za modalno određivanje građevina [19][20][21][22]. Ovaj brzi i relativno jednostavan postupak prihvatio je i vlasnik građevine, Područna uprava za nacionalne palače, jer omogućuje ispitivanje palače Beylerbeyi bez restrikcija glede njenog korištenja.…”

Istraživanje mehaničkih svojstava ziđa povijesnih zidanih građevina U ovom se radu određuju mehanička svojstava ziđa povijesne palače Beylerbeyi. Primijenjen je posredan postupak jer vlasnik nije dopustio uobičajena ispitivanja. Na početku je određena mineraloška struktura prvobitno ugrađenog morta. Kasnije su pripremljeni i u laboratoriju ispitani uzorci morta i ziđa. Dobivena mehanička svojstva korigirana su dinamičkom identifikacijom da bi se odredio stvaran modul elastičnosti ziđa. U tu je svrhu obavljena analiza okolnih vibracija te je za palaču izrađen i podešen model konačnih elemenata. Na kraju su korigirani parametri čvrstoće ziđa. Investigation of mechanical properties of masonry in historic buildingsMechanical properties of masonry from the historic Beylerbeyi Palace are analyzed in the paper. The indirect procedure was used as the owner did not allow usual testing. The mineralogical structure of the original mortar was initially determined. This was followed by preparation and laboratory testing of mortar and masonry samples. Mechanical properties obtained were corrected through dynamic identification so as to determine the real modulus of elasticity of the masonry. To this aim, an ambient vibration survey was performed, and the finite-element model of the palace was constructed and tuned. Finally, the strength parameters of the masonry were corrected.

“…Owing to the uncertainties in the behaviour of backfill material, experimental methods have been used to verify the analytical behaviour (e.g. Bayraktar et al, 2009). When laboratory or field results are compared with numerical results there are often differences in the results, and it is thought that the finite-element model of the bridge should be updated by changing uncertain modelling parameters such as material properties or boundary conditions to eliminate differences as much as possible.…”

This paper investigates the use of solid and hollow core voussoir blocks in an innovative FlexiArch bridge system. The system is formed from precast concrete voussoirs connected by a polymeric reinforcement, enabling the arch to be built and transported as a flat pack and lifted into shape after delivery to site, thus avoiding the use of centring for construction. This research is novel in that it trials and compares the use of hollow core and solid FlexiArch rings in third-scale models with granular backfill. The use of hollow core voussoirs reduces the loading on the polymeric reinforcement during construction and should allow for increased spans. This paper presents the test results of two similar third-scale 5 m 6 2 m (span 6 rise) arch systems, using both solid and hollow construction. The use of hollow core voussoir blocks reduces the weight of the system. Non-linear finite-element analysis (NLFEA) has been used to further compare arch behaviour and the thrustline position.
