Abstract

The effects of tenon depths and bolt constraint conditions on the mechanical behavior of semi-rigid joints of wooden historical buildings in Taiwan were examined. Monotonic and cyclic loading tests were performed on the joint specimens to obtain the moment-rotation relationship of wooden semi-rigid joints. The results showed that the wood joints could bear external lateral forces when they reached their yield strength and would not rupture immediately. The smaller the d/h (ratio of the tenon depth to beam height) value, the easier the joints collapsed during monotonic loading. The larger the d/h value, the larger the differences of the ultimate strengths. The tenon depth could be increased to strengthen the ultimate moment of the bolt. Comparing the experimental results and the results predicted by the Colson and Louveau model, the model with the proposed parameters could simulate the experimental results with a good accuracy, and the average absolute error was less than 7.6%.
