Abstract

Tema ovog završnog rada je proračun normalnih naprezanja i određivanje progiba nosača za slučaj poprečnog ravninskog kosog savijanja. Objašnjena je razlika između običnog i kosog savijanja te kada dolazi do kosog savijanja. Teorijski je objašnjeno čisto koso savijanje kao i koso savijanje silama, oboje potkrijepljeno skicama i izrazima koji se kasnije koriste u proračunu normalnih naprezanja. Također, ukratko je opisana deformacija nosača kod kosog savijanja, odnosno način određivanja progiba uz postupke grafoanalitičke i analitičke metode. Postupak proračuna prikazan je na dvama numeričkim primjerima koji su korak po korak razrađeni i potkrijepljeni skicama i izrazima.

Abstract (english)

The topic of this final paper is the calculation of normal stresses and the determination of beam deflection for the case of transverse plane unsymmetrical bending. The difference between ordinary and unsymmetrical bending and when unsymmetrical bending occurs is explained. Pure unsymmetrical bending as well as forced unsymmetrical bending are theoretically explained, both supported by sketches and expressions later used in the calculation of normal stresses. Furthermore, the deformation of the support during unsymmetrical bending is briefly described, that is, the method of determining the deflection with the procedures of graphoanalytical and analytical methods. The calculation procedure is shown on two numerical examples that are elaborated step by step and supported by sketches and expressions.
