Research on Mechanical Properties of Ban Mortise-tenon Joint of the Traditional Timber Buildings in the South Yangtze River Regions
摘要
Abstract
The mechanical properties of the Ban mortise-tenon joints of the ancient traditional timber buildings in the South Yangtze River Regions were studied with the experimental and theoretical methods. The tested mortise-tenon joints include three Ban mortise-tenon joints.The failure modes,the hysteretic curves,the skeleton curves,the rotation rigidities of this kind of mortise-tenon joint under low cyclic load-ing were obtained.The results show that the hysteretic curves of the Ban mortise-tenon joints appear to be the Z shape and have the obvious pinch effects.During the process of the test,these mortise-tenon joints orderly pass through the elastic stage,the yield stage and the failure stage.Furthermore,with the consid-eration of the nonlinear contact influence of the mortise-tenon joint and the nonlinear stress-strain behavior of the timber material,the mechanical properties of the Ban mortise-tenon joints were analyzed by ANSYS software.The theoretical results agree well with the experimental results.The relationship of in-plane ro-tational rigidity,the out-of-plane rotational rigidity and the tortional rigidity of the Ban mortise-tenon joint is achieved,the ratio of them was 1.4∶1.0∶1.1.The results can provide the theoretical basis for compu-ting analysis and repair design of the traditional timber buildings in the South Yangtze River Regions.关键词
