The influence of masonry infill on the behaviour of frame structures

Cilj diplomskog rada je prikazati utjecaj zidanog ispuna na ponašanje okvirnih konstrukcija. Za zadanu konstrukciju poslovne namjene koja je definirana projektnim zadatkom od strane mentora prikazana je analiza opterećenja koja djeljuju na konstrukciju prema lokaciji u Osijeku. Uz dimenzioniranje osnovnih nosivih elemenata konstrukcije proračunat je utjecaj seizmičkog proračuna na konstrukciju prema dva modela. Prvi model sadrži isključivo masu zidanog ispuna kako bi se vjerno prikazala masa konstrukcije pri seizmičkom proračunu, dok drugi proračunski model sadrži prikazan utjecaj zidanog ispuna na nosivu konstrukciju preko metode jedne zamjenske dijagonale. Sama konstrukcija je koncipirana na način da se sastoji od greda i stupova uz zidani ispun. Dispozicijskim rješenjem je prikazana geometrija konstrukcije koja je dimenzija 18 x 18 m, visine 18 m. Stupovi su proračunati s HEA profilima, a glavne nosive grede s HEB profilima. Svi elementi se izvode kvalitetom čelika S355. Proračun konstrukcije je proveden korištenjem programskog paketa SCIA Engineer.The aim of the thesis is to show the influence of masonry infill on the behavior of frame structures. An analysis of the loads distributed on the structure according to the location in Osijek is presented for the given construction for business purposes, which is defined by the project assignment by the mentor. Along with the dimensioning of the basic load-bearing elements of the structure, the impact of the seismic calculation on the structure was calculated according to two models. The first model contains only the mass of the masonry infill in order to accurately represent the mass of the structure during the seismic calculation, while the second calculation model contains the displayed influence of the masonry infill on the load-bearing structure through the method of one substitute diagonal. The construction itself is designed in such a way that it consists of beams and columns with masonry filling. The layout solution shows the geometry of the structure, which has dimensions of 18 x 18 m and a height of 18 m. The columns are calculated with HEA profiles, and the main load-bearing beams with HEB profiles. All elements are made of S355 steel quality. The calculation of the structure was carried out using the SCIA Engineer software package
