摘要
通过对保国寺大殿结构振动特性现场测试,得到大殿时程分析和频谱分析,结合建筑结构、材料以及使用现状,建立有限元分析模型,并用模态分析验证该建模的真实性。结合宁波地区场地条件,通过该有限元模型在不同烈度地震作用下的反应,评定地震破坏程度。根据现场调查及模型分析结果给出保国寺大殿维护与加固建议。
By in-situ vibration characteristic testing of the main hall of Baoguo Temple,got time history analysis and spectrum analysis data,combined with architectural structure,materials and current usage,finite element analysis model is established,modal analysis is used to verify the authenticity of the model.Combined with site conditions in Ningbo,earthquake damage degree is evaluated by the response of the finite element model to earthquake with different intensity.According to the results of site investigation and model analysis,suggestions for maintenance and reinforcement of the main hall of Baoguo Temple are given.
