基于斗拱构造的故宫古建筑抗震性能研究
Aseismic Performances of Ancient Buildings of the Forbidden City Based on Constitution of Dougong(Tou-Kung)
摘要
Abstract
To effectively protect ancient buildings of the Forbidden City,the aseismic performances of tou-kung is studied by simulation and static dynamic experimental means.The tou-kung of Taihe Pal-ace is selected to study its aseismic contribution to the whole structure,and its seismic performances is also studied,thereby obtaining key seismic parameters.A 1∶2 scale model of porch of Nansansuo-buildings is built,its seismic performances of under conditions of high-intensity earthquakes based on tou-kung constitution is obtained.Results show that tou-kung constitution contributes highly to seismic resistance of the structure.Energy dissipation capacity of tou-kung mainly comes from the extrusion effect among its components under the condition of its small deformation;while from friction sliding a-mong its components under its large deformation.Under high-intensity earthquakes,tou-kung is hardly destroyed,demonstrating excellent aseismic performances.关键词
