木结构古建筑抗震性能参数分析
Parametric analysis of seismic performance of ancient timber-framed buildings
摘要
Abstract
The different structural forms and their parameters directly affect the dynamic characteristics and seismic performance of the ancient timber-framed buildings.The influence of the change of the parameters on the dynamic performance of the structure is studied by the finite element modeling and parameter analysis.It will provide reference for the repair and reinforcement of ancient timber-framed buildings.Based on the model of a single-storey place house made by Ying Zao Fa Shi of the Song Dynasty,a 3-D beam-spring FEM model is established,which involves the sliding isolation of column root,energy dissipation of Dou-gong and semi-rigid behavior of mortise-tenon joints.Then a comparison is made with the shaking table test under unidirectional earthquake excitations.Furthermore,a parametric analysis is conducted through the change of structural configuration such as mortise-tenon joint,Dou-gong and roof and corresponding parameters.The results show that:with the increase of the lateral stiffness of Dou-gong,the natural frequency of the whole structure converges to the upper limit of 2.08 Hz,the ability of shock absorption of the structure becomes weaker.With the increase of mortise-tenon joints stiffness,the natural frequency of the whole structure converges to the upper limit of 3.26 Hz,while the slippage of the column increased and the lateral displacement of the column reduced.With the reduction of the stiffness of the mortise-tenon joints,the slippage of the column reduced while the lateral displacement of the column increased at the same time.The influence of the stiffness change of the mortise-tenon joints on the building's natural frequency is greater than that of the Dou-gong.The natural frequency of the structure reduced by the increase of the roof mass,while the deformation of the Dou-gong increases and helps improve the seismic capacity of the whole structure.关键词
