Structural Analysis of a Precast Large-panel Wall Building

U diplomskom radu je prikazan statički proračun i dimenzioniranje armiranobetonske stambene zgrade, koja se sastoji od prizemlja i tri kata, tlocrtnih dimenzija 13,2 x 38,0 m. Osnovni nosivi sustav zgrade čine poprečni zidovi na razmaku 6,3 m debljine 25 cm, dok je stropna konstrukcija omnia-ploča. Svaki se poprečni zid sastoji od 8 predgotovljenih panela dimenzija 6,6 x 2,8 m (profilirani posmični spoj). Razmatrano je ponašanje zidnih panela uslijed potresnog djelovanja. Analizirana su dva poprečna zida – jedan bez otvora, a drugi s otvorom koji je promatran kao povezani zid. Trošenje energije ostvaruje se u veznim gredama iznad otvora te klizanjem duž vertikalnih spojeva zidnih panela. Primijenjen je princip slabi vertikalni spoj i jaki horizontalni spoj. Prikazani su armaturni nacrti zidnih panela.This final year project presents the structural analysis and design of a reinforced concrete residential building, with ground floor dimensions 13,0 x 38,0 m, consisting of ground floor and three storeys. The basic loadbearing system may be described as a cross-wall system where the load-bearing walls of thickness 25 cm are provided at 6,3 m distances perpendicular to the longitudinal axis of the building. Each wall consists of eight precast panels 6,6 m long and 3,0 m high with indented shear joint. The floor system is based on omnia-plates (thin prefabricated plates with in-situ concrete topping). The behaviour of wall panels under seismic actions was considered. Two different cross walls were analysed – one solid wall and one wall with openings (considered as coupled wall). The dissipation of seismic energy is achieved in coupling beams above the openings and through shear sliding across the vertical joints. The principle of weak vertical and strong horizontal connection has been applied. Reinforcement drawings are provided for the analyzed wall panels
