Structural analysis of upgrade of residential building

Cilj ovog rada je dogradnja postojeće konstrukcije stambene građevine spregnutim materijalom. Objekt je osnih tlocrtnih dimenzija 7,3 x 50,63 m, a nalazi se strogom centru grada Zadra. Statička analiza konstrukcije izvršena je programskim paketom Autodesk Robot Structural Analysis Professional 2015 na 3D prostornom štapnom modelu. U proračun se ušlo pod pretpostavkom da je postojeće prizemlje objekta dovoljno čvrsto te da može podnijeti djelovanja dodanog kata istih tlocrtnih dimenzija. Ulazni podaci za proračun dobiveni su analizom djelovanja koja je provedena u skladu s Eurocode 1 normom te pripadajućim Nacionalnim dodacima. Proračun priključaka proveden je u skladu s Eurocode 3 normom. U analizi djelovanja su uzeta u obzir djelovanja vjetra, snijega, potresa te uporabno opterećenje građevine. Potresno djelovanje uzeto je u obzir zbog ravne katne (krovne) spregnute ploče koja se nalazi na visini od 10,0 m mjereći od tla. Svi elementi konstrukcije proračunati su po mjerodavnoj kombinaciji grupe elemenata u kojoj se nalaze, na način da zadovoljavaju zahtjeve stabilnosti i mehaničke otpornosti graničnog stanja nosivosti te graničnog stanja uporabivosti.The goal of this worktheses is to project and upgrade the existing residential building with composite material. The object of the half axis dimensions 7,3 x 50,63 m, is situated in town center of Zadar. The static analysis of the structures was carried out with the programming package Autodesk Robot Structural Analysis Professional 2015 on 3D spatial rod model. It is assumed that the existing ground floor is in good condition and strong enough for carrying the additional floor with same dimensions. The input data of the calculation were obtained through the activity analysis carried out in accordance with Eurocode 1 norm and its National additions. The calculation of the ports was conducted in accordance with Eurocode 3 norm. The activity analysis was carried out in regard to the effects of wind, snow, earthquake and in the usage load. The earthquake activity was taken into account due to the floor composite construction that is located on the height of 10,0 m measured from the ground. All elements of the construction were calculated in regard to the applicable combination of groups of elements in which they are located, in the way to meet the requirements of stability and mechanical resistance of the ultimate limit state and the serviceability limit state
