Abstract
A dual-layered wooden HP-shell was used for the Yamadera Post office. The layers, crossed relative to each other, are constructed of white wood boards connected with lag screws and further reinforced by aramid fiber sheet. Due to the complexity of this construction, the structural characteristics are not obvious. Therefore, the white wood material and the laminated wood panel of the HP shell were tested. The results of these experiments are as follows. 1. The bending performance of a laminated wood panel is equivalent to the performance of the one layer of the directions of an axis. 2. It is possible to increase the shear strength and the rigidity of the laminated wood panel by aramid-fiber reinforcement.
