In the paper are presented some of the acquired experiences in designing and construction of bridge structures in several countries, with a special attention to the analysis of support zones and expansion joints behavior of a number of road bridges. During destruction or damage of bridges, there is a small probability, but still there, that the human lives might be endangered (Kobe, Japan 17th January 1995); what is likely, however, is that it will be very difficult to help the injured in the region. Considering that the characteristics of removal of supports has a great influence on the behavior of the entire bridge structure, the design of support joints and connections must be paid due attention. In the recent decades, efforts are made to enhance research of all engineering structure, and thus the bridge structures and their weak points.
Key words: bridges, bearings, expansion devices, design

KONSTRUISANJE OSLONAČKIH ZONA BETONSKIH MOSTOVA ZA UTICAJE DELOVANJA STATIČKOG I DINAMIČKOG OPTEREĆENJA
U radu će biti prikazana neka od stečenih iskustva projektovanja i građenja mostovskih konstrukcija iz više zemalja, sa posebnim osvrtom na analizu ponašanja oslonaca i dilatacionih spojeva određenog broja drumskih mostova. Pri oštećenju i rušenju konstrukcija mostova postoji relativno mala verovatnoća, mada nije isključeno, da direktno budu ugroženi ljudski životi (Kobe, Japan 17.01.1995. godine); ali nastaju teškoće pri ukazivanju pomoći povređenima u tom regionu. Obzirom što karakteristike razmicanja oslonaca imaju veliki uticaj na ponašanje cele mostovske konstrukcije, to se konstruisanju osloničkih veza i spojeva mora posvetiti odgovarajuća pažnja. Poslednjih decenija čine se napori ka povećanom izučavanju svih inžinjerskih konstrukcija, pa samim tim i konstrukcija mostova i njihovih slabih mesta.
