A retegelt-ragasztott fatartok egyre elterjedtebbe valtak az elmult 50 evben. A megfelelő minősegű anyagokbol keszitett retegelt-ragasztott tartok minősegi beszerelest es uzemeltetest kovetően időtalloak, azonban egyre tobb esetben fordul elő a retegelt-ragasztott tartok karosodasa es a karosodas miatt egesz tetőszerkezetek eletveszelyesse valasa. Ebben a cikkben a retegrepedesek es tonkremenetelek okaihoz kapcsolodo mechanikai vizsgalatok es azok eredmenyei kerulnek bemutatasra. A mechanikai vizsgalatok celja, hogy probatest szinten megallapitsuk a ciklikusan valtozo klimatikus kornyezet (hőmerseklet, paratartalom) hatasat az RR tartok faanyagara es annak ragasztasi sikjaira. Mivel a faanyag rostra merőleges huzoszilardsaga es nyiroszilardsaga csekely, a tartokon kialakult delaminacio oka, ezen feszultsegek szilardsagot meghalado mertekeben keresendők. Az elvegzett vizsgalatok is a ket szilardsag meghatarozasara ill. a ciklikusan valtozo klimatikus kornyezet ezen szilardsagokra gyakorolt hatasara iranyultak. = Glue laminated timber beams have been used in an increasing number of cases in the past 50 years. Glue laminated beams are durable constructs if they are manufactured from adequate quality materials and if their installation and operation are performed to a high quality standard. There are however an increasing number of cases of glue laminated beams suffering damage and as a result entire roof structures becoming life-threatening. In this paper we present the mechanical tests and their results related to the causes of delaminations and failures. The purpose of mechanical tests is to determine the impact of the cyclically changing climatic environment (temperature, humidity) on the material and the gluing planes of glued laminated timber structures on a test specimen level. Since timber has low tensile and shear strength normal to grain, the cause of delamination in the structures is to be sought in the excess of stress exceeding the strength. The performed tests focused on the determination of the two strength values and the impact of the cyclically changing climatic environment on these strengths.
