Abstract (Croatian)

U sklopu ovog rada izrađene su tablice za odabir optimalnih okruglih cijevi za nosač konzervatora, tablice za odabir optimalne debljine zavara te tablice za optimalne fiksacijske vijke. Odabrane cijevi, zavari i vijci zadovoljavaju sve uvjete čvrstoće i stabilnosti u skladu sa navedenom literaturom. U drugom dijelu rada izrađene su tablice za odabir optimalnih kvadratnih i pravokutnih profila koji bi potencijalno zamijenili okrugle cijevi te su njihove mase uspoređene sa masom nosača od okruglih cijevi. \Na temelju te usporedbe predloženo je standardno rješenje za nosač konzervatora. U zadnjem dijelu rada je izvršen numerički proračun na potres predloženog standardnog rješenja te su određeni limiti dopuštenog potresnog opterećenja bez strukturalnog oštećenja nosača i gubitka njegove funkcionalnosti.

Abstract

As part of this work tables for selecting the optimal round pipes for conservator carrier, tables for selecting the optimum weld thickness and tables for optimal fixation screws are made. Selected pipes, welds and bolts meet all the conditions of strength and stability in accordance with the cited literature. In second part of the work are made tables to select the optimal square and rectangular profiles that could potentially replace the round pipes and their masses are compared with the mass of round pipes made carriers. Based on this comparison, it was proposed standard solution for conservator carrier. In the last part of the work has been carried out numerically seismic calculation of proposed standard solution and there were determined certain limits on the allowable seismic load without structural damage to the carrier and the loss of its functionality.
