摘要:
古建筑木柱浮搁于础石，其空间力学性能与结构地震响应密切相关.提出了基于纤维梁柱单元的古建筑木柱空间受力分析模型，根据柱脚局部受压确定古建筑木柱纤维截面网格尺寸划分原则，使用只压材料反映古建筑木柱受压不受拉特性，通过设置材料应变间隙考虑柱底与础石的接触缺陷.分析了模型对材性参数和应变间隙的敏感性，给出了模型应变间隙的取值方法，并基于已有试验验证了模型的正确性.进一步对模型施加空间荷载和地震机理，获取了其空间力和位移特性，结果表明：模型具备反映古建筑木柱空间力学性能的能力，可应用于结构抗震分析.
Abstract:
Traditional timber columns rest on stone bases and their spatial performance is closely related to the seismic responses of structures. In this paper a spatial analysis model was proposed for traditional timber columns based on fiber beamcolumn elements. The meshing principles of fiber sections for traditional timber columns were specified according to the local compression of column bottom. A compressiononly material was used to reflect the nontensile characteristics of traditional timber columns, in which strain gap was incorporated to consider the contact defects between column bottom and stone base. The sensitivity of the model to material properties and strain gap was analyzed, and the method for determining the gap strain was given. Further, the validated model was subjected to spatial loading and earthquake excitations, and spatial load and displacement characteristics were obtained. The results show that the model has the ability to reflect the spatial mechanical properties of ancient timber columns and can be applied to structural seismic analysis.
