Truss beams
For the realisation of larger spans in roof structures (> 30 m), lattice girders represent an architecturally appealing, economical and resource-saving alternative to solid wall girders made of glulam. The timber truss usually consists of continuous chords to which the diagonals and/or posts are hinged. A common and simple variant for forming these connections are bar dowel connections. Due to the predominant normal force stress in the struts and chords of such beams, the use of homogeneous glulam makes sense.
