dc.description.abstract | Širokopojasne profile sa paralelnom konturom pojaseva, koji se danas dominantno koriste za izradu jednošinskih nosača dizalica, karakteriše relativno veliki radijus tranzicije konture pojasa u konturu rebra. Upravo zbog toga, uticaj pomenutog radijusa na naponsko stanje izazvano lokalnim savijanjem usled dejstva točkova dizaličnih kolica znatno je izraženiji kod širokopojasnih (IPB) profila, u odnosu na klasične I profile i srednje široke (IPE) profile. U radu su prezentirani rezultati numeričko-analitičkog i eksperimentalnog istraživanja lokalnih napona u zoni tranzicije donji pojas/rebro kod širokopojasnih profila. Utvrđeno je da se najveće vrednosti razmatranih napona javljaju na početku tranzicije konture, a ne u tački fiktivnog preseka konture rebra i donje konture donjeg pojasa, kako se navodi u relevantnoj literaturi i aktuelnoj tehničkoj regulativi (standard EN 15011:2014). Osim toga, rezultati istraživanja dokazuju da apsolutne vrednosti lokalnih napona na donjoj i gornjoj konturi nisu jednake. | sr |
dc.description.abstract | Wide flange I-beams with parallel flange contours, which are now predominantly used in production of monorail crane girders, are characterized by a relatively large radial transition between flange contour and rib contour. Therefore, the influence of the radius on the stress state, due to the local bending caused by the action of crane trolley wheels, is more pronounced in wide-flange I-beams (IPB) than in conventional (I) and mid-wide (IPE) I-beams. This paper presents the results of numerical-analytical and experimental research of local stresses in the lower flange-rib transition zone at wide flange I-beams. It was found that the highest values of the considered stresses occur at the start of the transition contour, and not in the fictive point of intersection of the rib contour and the upper contour of the lower flange, as stated in relevant literature and current technical regulations (standard SRPS EN 15011: 2014). In addition, research results show that the absolute values of local stresses on the lower and upper contours of the lower flange are not equal. | en |
