青城山黄帝祠砖木古建筑震害数值仿真研究
|
摘要
5.12汶川地震中,青城山古建筑表现出了较好的抗震性能,损毁较少,典型的如黄帝祠,震后相对完好,但其底层下柱段局部附带石墙裙的部位,砖柱破坏较为严重。据此,根据青城山古建筑群的震后调查,采用数值仿真手段,重点研究了黄帝祠不同材质墙裙对底层柱动力响应的影响、不同构件约束刚度对整体结构响应的影响,为此类建筑改造和震后加固提供参考。
The ancient buildings on Qingcheng Mountain show good anti-seismic capability and there is a little damage of those buildings in the Wenchuan Earthquake.Yellow Emperor temple is the typical building which damage is only on the bottom of brick column with stone dado in the ground floor.Based on the investigation of the ancient buildings,by useing numerical simulation,the effect of different dado material on the dynamic response of the ground floor column and the different restrict stiffness on the response of the total structure is studied in this paper.The results can be referred on the reconstruction and reinforce after the earthquake of those kind of buildings.
