    Abstract

    A short summary of research series made at VTT on joints of glulam structures based on at skew angles into the glulam glued-in ribbed steel rods is reported. Standard prefabricated steel members to be glued into the glulam elements have been developed. The element consists of two steel members, one for tension and one for compression forces. The slotted contact surfaces of the members are bolted together. In construction the glulam elements will be connected with bolts or only with nuts and no welding on site will be needed. This paper presents the design of these connections and test results of their loading as well as test results of fire resistance tests under loading. Design method is based on the yielding of the tensile rods. Real glulam structures have been designed and built. The main concern is on ease of manufacturing and construction with standardised steel elements as well as fire safety.
