Abstract [sv]

Utvecklingen av förbandsmetoder är viktigt för att utveckla konstruktionslösningar. Under det senaste decenniet har forskning på limmade förband utförts, främst på inlimning av stålstag och plattstål i limträ. Förhoppningen är att spänningen ska fördelas jämnare i förbandet och att brott ska kunna undvikas. Hypotetiskt sett skulle det kunna göra knutpunker utan synliga förband möjliga vilket även skulle gynna arkitekternas önskemål.

Genom en sammanställning av tidigare forskning dras en jämförelse mellan testresultaten och en antagen knutpunkt som belastas av egentyngder och variabla laster. På så sätt kan limmets kapacitet konkretiseras. Även problematik som uppstår och förutsättningar som måste utvecklas redovisas.

Abstract [en]

The development of joints for wood structures has been under progress during the last decade, and research has mainly been done on glued in steel rods and inner steel plate joints. The aim of this report is to find a way to get a better shear resistance to prevent timber structures from breaking during high risk circumstances, such as loads caused by exceptional weather. Structures without visible joints would also benefit the architects' wishes, which would be a reason to develop the technique of joints for wood structures.

By a compiling of previous research, a comparison between test results and a joint of a hypothetical building is made. The loads that affect the calculations of the joint are snow-, wind-, variable and structural loads. This concretises the capacity of the adhesive joint. Also problems that appear and preconditions that have to be developed are recited.
