Abstract

U radu je ispitan inovativni sustav prošupljenih drvenih elemenata za izvedbu blok gradnjom drvenih kuća s ciljem određivanja nosivosti na trenje između elemenata blok sustava. Uvodni dio sadrži opće karakteristike drva i LLD elemenata. Nakon toga je opisano ispitivanje prošupljenih elemenata koje je provedeno u laboratoriju Građevinskog fakulteta u Zagrebu. Svrha ispitivanja je određivanje koeficijenta trenja između dva drvena elementa povezana ljepljivom trakom. Taj podatak nam je ključan za numeričko modeliranje kontakta između elemenata i statički proračun konstrukcije. Također, u računalnom programu Dlubal RFEM modelirani su uzorci na kojima se vršilo ispitivanje kako bi poboljšali nosivost za koju je ključna završna obrada kontaktnih ploha.

Abstract (english)

The paper examined an innovative system of hollow wooden elements for the construction of block wooden houses with the aim of determining the bearing capacity for friction between the elements of the block system. The introductory part contains the general characteristics of wood and LLD elements. After that, the testing of hollow elements, which was carried out in the laboratory of the Faculty of Civil Engineering in Zagreb, is described. The purpose of the test is to determine the coefficient of friction between two wooden elements connected by adhesive tape. This information is crucial for numerical modeling and static calculation of structures. Also, in the software Dlubal RFEM, samples were modeled on which the test was carried out in order to improve the load-bearing capacity, for which the final treatment of the contact surfaces is crucial.
