Bamboo PSL (bamboo parallel strand lumber) showed the potential to be used as bending and compression members. Therefore, rotational stiffness test was carried out in order to study the practical use of the bamboo PSL joints. The material of bamboo PSL was used an average moisture content of 7.5% of Moso-chiku (Phyllostachys heterocycla f. pubescens Muroi). Adhesive for bonding bamboo strands was used aqueous polymer isocyanate-based. Joints of L-shaped specimens were constructed bamboo PSL members of the length 600 mm in cross-section 90 mm. Rotational stiffness tests were repeated three times each from 1/450 to 1/30 rad of deformation angle. Experimental results were maximum moment:4.4 kN·m, deformation angle:0.114 rad and rotational stiffness:65 kN·m/rad. In order to determine the rotational stiffness of the joints of the bamboo PSL, it is necessary to perform properly the crooss-sectional design of the members.
