Experimental Studies on Glue-Laminated Bamboo Trusses

Prefabricated light-frame bamboo trusses are widely used in light-frame construction as the main vertical load-carrying elements in roof and floor systems because of their long-span capabilities, ease of use, versatile configuration, rapid installation, and competitive cost. This paper presents experimental studies on glue-laminated bamboo trusses. Six full-scale model trusses with two types of configuration and sizes were tested to failure under gradually increased vertical load. The failure of the model trusses was caused by lateral buckling of the top chords. Tests show that the modern glue-laminated bamboo trusses have adequate stiffness and strength.
