Abstract

Provedeno je dimenzioniranje osnovnih elemenata visoke armiranobetonske poslovne zgrade dvostrukih ovalnih tlocrta povezanih mostom, upotrebom statičke i dinamičke analize pomoću računalnog programa SCIA Engineer. Analizom opterećenja obuhvaćena su sva karakteristična djelovanja na području grada Zagreba (snijeg, vjetar, potres, geometrijske imperfekcije). Kako bi se dokazao utjecaj povezivanja dviju zgrada mostom na povećanje krutosti konstrukcije tijekom horizontalnog potresnog opterećenja, provedena je usporedba perioda vibracija, vlastitih oblika, međukatnih pomaka i pomaka vrha zgrade sa samostalnom zgradom istog tlocrta. Dimenzioniranje ovalne ploče međukatne konstrukcije i mjerodavnih posmičnih zidova armiranobetonske jezgre provedeno je prema graničnom stanju nosivosti i uporabljivosti. Granično stanje nosivosti obuhvaća proračun uzdužne i poprečne armature, proboja ploče, kontrole izvijanja zidova te proračun nosivosti zidova u potresnom području, dok granično stanje uporabljivosti podrazumijeva ograničenje širine pukotina i progiba ploče te ograničenje tlačnih naprezanja u zidovima prizemlja.

Abstract (english)

Using static and dinamic analysis with computer software SCIA Engineer, dimensioning was conducted on basic elements of highrise reinforced concrete office buildings with double oval layout buildings connected with a bridge. Load analysis comprised all typical loads specific for City of Zagreb, such as snow, wind, earthquake and geometrical imperfections. In order to prove significant increasing stiffness of a construction (two buildings joined with a bridge) during horizontal seismic load, comparative analysis of vibration periods, mode shapes, inter-storey drifts and displacements of the top of a building with the same single oval layout building was conducted. Dimensioning oval slabs and relevant shear walls was conducted according to ultimate limit state and serviceability limit state. Ultimate limit state comprises calculation of vertical and horizontal reinforcement, punching design, limitation of wall deflections and calculation of shear walls in seismic area. Serviceability limit states checks comprise limitation of crack width, deflections of a slabs, and limitation of compressive stress in groundfloor walls.
