摘　　要：榫卯连接是我国古建筑木结构的特有构造形式,其完整性直接影响古建木结构的抗震性能。为此,以古建木结构中较为常见的燕尾榫为例,通过对其传力机理进行理论研究,建立其数值模型和弯矩-转角(M-θ)力学模型。研究结果表明,根据模型计算获取各个特征值与实验数据的偏差均低于20%。这表明研究构建的模型精度较高,能够较为准确地评估建筑的抗震性能。研究为古建筑的修缮和加固提供数据保障。The research of ancient buildings has been focus on protection,repair and reinforcement in construction industry.Timber structures and mortise-tenon joints are the main characteristics of ancient buildings in China,and the integrity of mortise-tenon joints often determines the seismic performance of ancient buildings.For this reason,a numerical model and a moment rotation(M-θ)mechanical model are established based on the analysis of the force transfer mechanism of dovetail joints,which are common in ancient timber structures.The results show that the deviation between each characteristic value calculated based on the model and the experimental data is less than 20%.This indicates that the model built in this study has a high accuracy and can accurately evaluate the seismic performance of ancient timber structures.The research provides data assurance for the repair and reinforcement of ancient buildings.
