古建筑木结构地震作用下的破坏分析及加固措施研究

Research on failure analysis and reinforcement measures of ancient timber structure under earthquakes

为了科学合理的对古建筑木结构进行修缮保护,根据古建筑木结构独特的营造技术,系统总结了古建筑木结构不同于现代建筑结构的优良的抗震构造特点;结合四川雅安地震后对古建筑木结构的震害调查,通过系统归纳和分类统计,对古建筑木结构的地基基础、梁柱和枓栱等构件、榫卯节点、整体稳定性以及围护结构在地震作用下的破坏情况及破坏原因进行详细的分析和探讨;并针对结构不同的破坏情况,提出相应的抗震加固方法。分析结果可为古建筑木结构的修缮加固提供理论依据。

In order to s cientifically and reasonably protect the ancient timber structures, according to the unique construction of ancient timber structures, it summarized their excellent seismic constitution characteristics that were different from modern architectures; Combined with the earthquake damage survey to the ancient timber structures after Ya'an earthquake, it took detailed analysis and discussion under the effects of earthquake damage to the ancient timber structures in terms of foundation, component such as beams and columns, mortise and tenon joints, overall stability and building envelope through summing up and classification and statistical methods; And in allusion to different structure damages, it put forward the corresponding seismic strengthening methods. Analysis result got can provide theory basis to the repair reinforcement of ancient timber structures.
