木结构古建筑结构特性的计算研究

NUMERICAL ANALYSIS ON STRUCTURAL ARACTERISTICS OF ANCIENT TIMBER ARCHITECTURE

  • 摘要: 对蕴藏丰富历史文化信息的中国古建筑的研究和保护是抢救中华文化遗产的重要内容。本文在木结构古建筑结构特性实验研究的基础上,通过定义和引入反映木结构古建筑斗栱与榫卯节点特性的半刚性节点单元,建立适合木结构古建筑特点的3维有限元计算模型和分析方法。研制了有限元动力分析软件SAFATS。利用现场实测和模型实验结果,采用Simplex方法反演推断半刚性节点平均刚度的范围。通过有限元动力计算以及与现场实验和模型实验结果的对比分析,获得了西安北门箭楼的前6阶振动模态。

     

    Abstract: There is an urgent requisite on the preservation of Chinese architectural heritages, since environmental and time impacts have been abating their structural resistance capability. Based on the experimental studies on an ancient timber structure in the proceeding companion paper, a semi-rigid element is defined and a 3-dimensional FEM model is developed in this paper. By comparing with measured results, the stiffness of semi-rigid element is deduced and dynamic characteristics of the front tower over Xi'an City Wall are obtained.
