Structural Analysis and Design of a Reinforced Concrete Office Building

U radu je proveden statički proračun i dimenzioniranje armiranobetonske zgrade, poslovne namjene, katnosti P+3, smještene na području Zadarske županije. Zgrada je pravilnog tlocrtnog oblika dimenzija 24,74 m x 24,74 m i visine 13,85 m, te se sastoji od tri polja u svakom smjeru. U sredini zgrade nalazi se atrij u kojem je predviđena komunikacija (stubište i dizalo). Međukatna konstrukcija je kazetirani strop s obodnim gredama. Vertikalnu nosivu konstrukciju čine zidovi međusobno povezani veznim gredama i stupovi kružnog poprečnog presjeka. Povezani zidovi zbog velike krutosti preuzimaju većinu horizontalnog opterećenja, što je i pokazano izradom ravninskog modela u kojem su okviri poredani jedan do drugoga, povezani krutim gredama u razini stropne konstrukcije, te opterećeni horizontalnim opterećenjem. Proračun djelovanja i dimenzioniranje nosivih elemenata konstrukcije provedeno je u skladu s važećim normama i nacionalnim dodacima (HRN EN 1990, 1991, 1992 i 1998). Za dimenzionirane elemente izrađeni su nacrti armature.This final year project deals with static analysis and design of a reinforced concrete office building, containing ground floor and three storeys, located in Zadar County. The building has a regular floor plan with dimensions 24.74 m x 24.74 m, height 13.85 m and consists of three spans in each direction. In the middle of the building there is an atrium where communication is provided (staircase and elevator). The floor structure is a waffle slab with perimeter beams. The vertical load-bearing structure consists of coupled walls and columns with a circular cross-section. Due to their high rigidity, the coupled walls collect most of the horizontal load, which was demonstrated by making a planar model in which the frames are lined up next to each other connected by rigid beams at the level of the floor structure, and loaded with horizontal loads. Load analysis and design of load-bearing members was carried out in accordance with valid standards and national annexes (HRN EN 1990, 1991, 1992 and 1998). Reinforcement drawings were made for the designed elements
