Abstract

Završni rad obrađuje temu sastavljenih drvenih nosača. Sastavljeni nosač je homogen u smislu materijala od kojeg je izrađen, ali nije monolitni nosač. Spoj lamela u sastavljenom drvenom nosaču može biti izveden različitim spojnim sredstvima. U radu je prikazan proračun lijepljenih lameliranih nosača i nosača lameliranih drvenim moždanicima. Provedeno je eksperimentalno ispitivanje savijanjem u četiri točke pri čemu su pomaci uzoraka mjereni induktivnim osjetilima. Rezultati ispitivanja prikazani su u obliku krivulja sila-pomak. Eksperimentalne vrijednosti uspoređene su s proračunskim za navedene tipove sastavljenih nosača.

Abstract (english)

The bachelor thesis deals with the subject of built-up wooden girders. Built-up girder is homogeneous in terms of the material from which they are made, but they are not monolithic beams. The connection of the lamellas in the built-up wooden beam can be done with different connecting means. Numerical calculations of glued laminated girder and dowel laminated girder is here presented. An experimental test was carried out by bending at four points, measuring the displacements with LVDT sensors. The experimental results are presented in the form of force-displacement curves and compared with the numerical calculations for the specified types of built-up girders.
