Experimental Study for Big Screw Joint with Cross Laminated Panel Part 1 Summary and Experiment 1

摘要

The purpose of this research is to improve performance of the joints used in Big Frame construction system. If the Big Screw is embedded into parallel direction to wood fiber direction, the joint performance has very high rigidity and high strength, however, it seems to be brittle. On the other hand, if the screw is embedded into cross direction, joint doesn't have so high rigidity. However, it has very high ductility. If we adopt cross laminated panel to this joint system, the system might have a character of both high rigidity and high ductility. To prove the performance of the joints made with cross laminated panels, we have done tensile experiments. By the results of tensile experiments, we prove that if we use cross laminated panel for this joint, we get characteristic with high performance. Then, we got the possibility that can control both rigidity and ductility by combinations of lamina.
