| Popis: | U radu je prikazano eksperimentalno određivanje nosivosti veza ostvarenih metalnim konektorima tipa WOLF i LKVC. S obzirom na kompleksnost veza ostvarenih ovim savremenim mehaničkim spojnim sredstvima, predmet rada obuhvaća samo nosivost bočne veze (naprezanje u spoju metal-drvo). Cilj provedenih eksperimentalnih ispitivanja je bio da se utvrdi nosivost bočne veze ostvarene metalnim konektorima, u skladu s odredbama Eurokoda 5 i da se paralelno s tim analizira odnos nosivosti ova dva tipa konektora, s aspekta njihove geometrije. Eksperimentalno ispitivanje je provedeno na više uzoraka, opterećivanjem uzoraka do dostizanja granične nosivosti bočne veze. Diskusija rezultata ispitivanja je obuhvatila analizu pomjerljivosti veza za različite nivoe opterećenja, kao i način dostizanja granične nosivosti bočne veze. U zaključku je dan komentar o utvrđenim graničnim nosivostima bočne veze, za određena pomjeranja veze, i zauzet je stav po pitanju dobivenih rezultata. This paper demonstrates the results of experimental determination of load bearing capacity of structural timber member connections realized by WOLF and LKVC metal connector plates. Considering the complexity of the connections realized by these modern mechanical fasteners, this paper deals only with plate anchorage capacity (stress in the metal-wood contact). The aim of the conducted experimental study was to determine the metal connector plate anchorage capacity in accordance with the provisions of Eurocode 5 and also to analyse the ratio of the load bearing capacities of these two types of connectors in terms of their geometry. Experimental testing was conducted by loading of multiple samples up to the limit plate anchorage capacity. Discussion of the test results included the analysis of the connection deformation for different levels of load, as well as the mode of reaching the limit plate anchorage capacity. Review of the determined limit plate anchorage capacities, for the determined displacements of connection, was given in the conclusion, together with the comment on test results. |
