Abstract

U diplomskom radu napravljen je dokaz pouzdanosti kompleksa koji se sastoji od čelične hale s kranovima i višekatne okvirne čelične zgrade. U prvom dijelu obrađena je dvobrodna hala gdje je izvršena statička i dinamička linearna analiza. Konstrukcija je dimenzionirana na unutarnje sile i prema njima su obrađeni priključci i temelji. Drugi dio obuhvaća statički i dinamički proračun višekatnog čeličnog okvira sa inovativnim sustavom vertikalne stabilizacije. Radi se o okviru sa ekscentričnim spregovima (dvojni sustav) koji sadrži potresne veze i proračunava se na način da se zamjenom potresnih veza, može vratiti u prvobitan položaj. Provjera dvojnog sustava izvršena je nelinearnom statičkom analizom postupnog guranja (pushover analysis) i dana je usporedba faktora ponašanja prema EC i faktora ponašanja dobivenog pushover analizom. Dodatno, u svrhu reduciranja konstrukcije, priključci su dimenzionirani kao djelomično nepopustljivi i provedeni su kroz linearnu dinamičku i nelinearnu statičku analizu. Na temelju rezultata uspoređeno je ponašanje sustava s krutim i djelomično nepopustljivim priključcima i u konačnici izveden zaključak cijelog rada.

Abstract (english)

In this master's thesis, reliability check of the complex consisting of steel single-storey building with cranes and a multi-storey steel frame building was made. In the first part, two-bay single- storey building was processed, where static and dynamic linear analysis was performed. The structure is dimensioned according to internal forces and connections and foundations are processed according to them. Second part includes static and dynamic analysis of a multi-storey steel frame with innovative vertical brace system. It is a frame with eccentric braces (dual system) that contains seismic links and is calculated in a way that by replacing the sesmic links, it can be returned to its original position. Dual system check was performed by nonlinear static pushover analysis and a comparison of behaviour factor according to EC and pushover analysis was given. Additionally, in order to reduce the building, connections were calculated as semi- rigid and carried out trough linear dynamic and nonlinear static analysis. Based on results, behaviour of the system with rigid and semi-rigid connections was compared and finally the conclusion of the whole thesis is given.
