Abstract. Two mathematical models for determining bolt elastic lines,
being eccentrically loaded by a working force, have been considered in
the paper. Based on the elastic lines defined, it is very easy to obtain
bolt bending stress, which at calculating such bolted connections might
not be neglected. An example of the calculation for a concrete bolted
connection has been given in the paper.
Key words: bolted connection, model, elastic line, force, bending
stress
ANALIZA MATEMATIČKIH MODELA U PROCESU
DEFORMACIJA EKCENTRIČNO OPTEREĆENIH ZAVRTNJEVA
U radu su razmatrana dva matematička modela, za određivanje elastične linije
zavrtnja, koji je opterećen ekcentričnom radnom silom. Na osnovu definisanih
elastičnih linija, veoma lako i brzo se dolazi do napona savijanja zavrtnja,
koji se pri proračunu ovakvih veza ne bi smjeli zanemarivati. U radu je
dat primjer proračuna za konkretnu zavrtanjsku vezu.
Ključne reči: zavrtanjska veza, model, elastična linija, sila,
napon savijanja.
