Abstract
U ovom radu razmatra se izvijanje štapa u plastičnom području. Za elastično izvijanje štapa prikazan je izraz za kritičnu silu izvijanja koja se naziva Eulerovom kritičnom silom. U plastičnom području izvijanja štapa detaljno su prikazana dva analitička postupka izračuna kritičnog naprezanja, Engesserov postupak i Engesser-Jasinski-Karmanov postupak. Prikazana je teorijska podloga empirijskih izraza, Tetmayerovog pravca, Johnsonove parabole, AISC krivulje, Rankine-Gordonove krivulje i Eurocode 3 krivulje. U numeričkom dijelu rada primijenjeni su neki od navedenih empirijskih izraza, Tetmayerov pravac, Johnsonova parabola i AISC kriterij. Na temelju eksperimentalno određene ovisnosti naprezanje – deformacija u području između granice proporcionalnosti i granice tečenja određena je krivulja kritičnog naprezanja u plastičnom području za puni i šuplji pravokutni presjek. Podatci koji su korišteni u proračunu su podaci za čelik S355J2C. Dobivena analitička rješenja uspoređena su s rješenjima empirijskih izraza.
Abstract (english)
In this thesis buckling of the beam in plastic region is considered. For elastic buckling of the beam expression for critical force called Euler critical force is presented. In plastic region two analytical procedures of critical stress calculation are presented in detail, Engesser and Engesser-Jasinski-Karman procedure. Theoretical basis of empirical expressions is presented, Tetmayer`s line, Johnson`s parabola, AISC curve, Rankine-Gordon curve and Eurocode`s 3 curve. In numerical part of the thesis some of the described empirical expressions have been applied, Tetmayer`s line, Johnson`s parabola and AISC criterion. Based on experimentally determined stress – strain curve in region between proportionality limit and yield stress critical stress curve in plastic region has been determined for full rectangular and hollow rectangular cross section. Data that have been used in calculation are data for steel S355J2C. Analytic results have been compared to results of empirical expressions.
