Abstract

U radu je provedena analiza i dimenzioniranje ĉeliĉne konstrukcije visoke graĊevine visine 172 metra sa 40 nadzemnih etaža koja je izvedena nosivim sustavom izvedene sustavom cijev u cijevi. Na odabranom sustavu istražen je utjecaj naĉina modeliranja meĊukatne konstrukcije na ponašanje graĊevine u sluĉaju statiĉkog i seizmiĉkog djelovanja. Nakon provedena analize opterećenja izraĊen je model konstrukcije u raĉunalnom programu SCIA Engineer te su provedene statiĉke i seizmiĉke analize i konstrukcija je dimenzionirana na mjerodavne uĉinke djelovanja. Razmatrana su tri naĉina modeliranja meĊukatne konstrukcije: plošni elementi, krute veze i zamjenske dijagonale. Analize odabranih naĉina modeliranja su pokazale da pojednostavljenje numeriĉkog modela predstavlja opravdan izbor pri modeliranju. Ova tvrdnja se osobito oĉituje u smanjenju broja konaĉnih elemenata kod alternativnih naĉina kruta veza ili zamjenske dijagonale što rezultira puno manjim utroškom vremena u odnosu na model s plošnim elementima. TakoĊer, u okviru rada, projektirani su prikljuĉci ĉeliĉnog nosivog sustava metodom CBFEM u programu Idea Statica te su izraĊeni pregledni nacrti i nacrti karakteristiĉnih detalja na temelju 3D modela konstrukcije u programu Tekla Structures.

Abstract (english)

This thesis contains analysis and design of a steel tube-in-tube structure that is 172 meters tall and consists of 40 aboveground floors. The influence that floor system modeling has on the behavior of a structure under static and seismic action has been researched on the chosen system. Upon completion of load analysis, a model of a structure was made using SCIA Engineer software for the purpose of conducting static and seismic analysis, after which the structure was designed with regards to its standard effects. Three methods of floor system modeling have been considered: shell elements, rigid links and alternative diagonals. Analysis of chosen methods of modeling has shown that simplification of a numerical model represents a valid option when modeling a structure. This statement manifests itself in the reduction of finite elements when using rigis arms or alternative diagonals, which represent a less time- consuming modeling method compared to the model with shell elements. This thesis also contains steel connection design using CBFEM method in Idea StatiCa software, as well as structural steel and detailing drawings that were generated using a 3D model which was made in Tekla Structures software.
