Optimizacija i analiza armiranobetonskih ravanskih nosača primenom metode pritisnutih štapova i zatega

Abstract

U disertaciji su analizirani armiranobetonski ravanski nosači primenom metode pritisnutih štapova i zatega. Optimizacija nosača urađena je diskretnom topološkom otimizacijom kojom se pun nosač zamenjuje ekvivalentnim rešetkastim. Dat je predlog algoritamskog dobijanja Strut-and-Tie modela koji je implementiran u program sopstvene izrade pod nazivom „ST method“. Provera pouzdanosti predloženog algoritma utvrđena je primerima iz referentne literature, sopstvenim eksperimentalnim ispitivanjem i numeričkom analizom u komercijalnim programima. Rezulatati analiza su pokazali da se predloženi algoritam u programu „ST method“ može koristiti za dobijanje Strut-and-Tie modela i njihovo dimenzionisanje i da se pri odabiru nekih modela mora koristiti inženjersko iskustvo.

In dissertation thesis, reinforced concrete plane members have been analyzed by the Strut-and-Tie method. Optimizing of the members is made by discrete topological otimization which replaces full member with equivalent truss system. Algorithmic manner of Strut-and-Tie model obtaining has been suggested, which is implemented in the program of an own creation called "ST method". The reliability of the proposed algorithm is determined by the examples from reference literature, an own experimental test and numerical analysis in commercial programs. The results of the analysis showed that the proposed algorithm in the "ST method" can be used to obtain Strut-and-tie models and their dimensioning and that in certain models, the engineering experience must be used.
