Abstract Tenon-mortise joint is widely used in traditional timber structures around the world. This paper summarizes the results of an experimental study of the structural behavior of tenon-mortise joints made with glulam and CNC technology instead of traditional material and manual work. 30 full-scale tenon-mortise joints were manufactured and tested under monotonic loading, and the effects of dimension, shape, processing error and adhesive were evaluated. It was found that the round rectangular shaped tenon-mortise joints were comparable with traditional joints in terms of structural performance, but were time and labor saving. The variability of the proposed tenon-mortise joints was lower, which… More >

Abstract Applying pre-stress in glulam beam can reduce its deformation and make full use of the compressive strength of wood. However, when the glulam with low strength and the pre-stressed steel with high strength form combined members, materials of high strength can’t be fully utilized. Therefore, this study puts forward the idea of regulating and controlling string beam of pre-stressed glulam. By regulating and controlling the pre-stress, a part of the load borne by the wood is allocated to the pre-stressed tendon, which is equivalent to completing a redistribution of internal force, thus realizing the repeated utilization of the wood strength… More >
