1 Introduction
1.1 Geotechnical background
1.2 Previous CLHS material property investigations
1.3 Endless CLHS production processes
-
wrapping fiber-reinforced polymer around the longitudinal CLHS butt joint (94% bending capacity)
-
longitudinal staggering of butt-jointed veneers within the section in a similar process to that used to construct LVL products (83% bending capacity).
2 Materials and methods
2.1 CLHS manufacturing and sampling
2.2 CHLS testing
2.3 CLHS finger jointing
