9This paper proposes a new method for beam-beam connections, which include 10 plywood as slot-in plates connected by oak pegs. A total of 96 specimens were 11 fabricated for tests to explore the minimum required end distances and spacing 12 between pegs parallel to the grain. A new failure mode, termed shear wedge that is 13 different from those found in previous research, was found. A spring model was also 14 proposed in this study to investigate the stiffness of the connections, and feasibility of 15 EC5 to be applied on the new proposed connections was also examined. The effective 16 number was discussed in this study and modified in accordance to the experimental 17 results. The result of this study shows the new connections proposed do not lead to 18 brittle failure unless failure in plywood occurred. 19 20
SUMMARYThis study investigates the structural performance of interior, exterior and corner traditional timber joints found in a traditional temple in Japan subjected to bi-axial bending. A total of 36 half-scale specimens were fabricated and tested under both uni-axial and bi-axial cyclic bending for comparison of their structural behaviour. The results show that the corner joints exhibit lower rotational stiffness than the interior and exterior joints. Further, connections subjected to only uni-axial moments exhibit better performance with regard to moment resistance, energy dissipation and stiffness degradation as compared with those subjected to bi-axial moments. Hence, this study suggests that if the timber joints are subjected to bi-axial bending, this effect on timber joints should be considered during the design and evaluation process in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
