The paper deals with a brief presentation of a part of the performed experimental tests of the prefabricated reinforced concrete structural system "AMONT"for construction of various types of modern industrial halls. The test results are analyzed for two industrial halls both constructed according to this structural system but in the different phases of construction, tested in the full scale by application of AMBIENT vibration method. From the obtained Fourier spectra for measured ambient vibrations in two orthogonal direction for the structure without walls and the other with façade and filling walls, a significant discrepancy in their natural frequencies has been observed, and some conclusions about the influence of panel walls on dynamic characteristic the frame structure have been drawn out. The paper used some data of the research after the earthquake in Montenegro which took place on 15th of April 1979.
Key words: Prefabricated reinforced concrete structure, panel walls, ambient vibrations, Fourier spectrum.
ANALIZA PONAŠANJA NOSEĆE KONSTRUKCIJE I ZAVRŠENOG OBJEKTA NA OSNOVU EKSPERIMENTALNIH ISPITIVANJA U PRIRODNOJ VELIČINI
U radu je ukratko dat prikaz dela sprovedenih eksperimentalnih ispitivanja montažnog armiranobetonskog sistema "AMONT"za izgradnju različitih tipova modernih industriskih hala. Analizirani su rezultati ispitivanja dve industrijske hale, obe izvedene u tom konstruktivnom sistemu ali u različitoj fazi izgradnje, u prirodnoj veličini primenom metode ambijent vibracija. Iz dobijenih Furijeovih spektara za merene ambijent vibracije u dva ortogonalna pravca za konstrukciju bez zidova i istovetnu konstrukciju sa fasadnim i zidovima ispune, uočena je značajan razlika u njihovim sopstvenim frekfencama i izvedeni su zaključci o uticaju zidova ispune na dinamičke karakteristike te ramovske konstrukcije.
