【摘要】 摘 要本文对中国古代建筑中的木结构和砖石古塔的结构特性和抗震性能进行了详细研究。关于木结构抗震和加固取得了以下方面的成果：(1)对于单层木结构古建筑，针对榫卯连接的半刚性，提出结合脉动测试结果的算法。(2)在有限元计算中，本文利用脉动测试结果，弹簧单元模拟榫卯和斗拱的半刚性，对木结构进行有限元分析。(3)根据动测所得到的结构特性，提出单自由度木结构震害预测的计算方法。(4)提出木结构的模糊震害预测方法。(5)算例对泉州开元寺大雄宝殿进行了有限元分析。并给出了不同的地震波作用下的结构时程响应和底部剪力。对于南方地区众多的砖石结构古建筑，项目组利用所收集的大量数据，结合现有方法预测区域震害，得到了一般性的规律。对于砖石古塔的震害预测，目前有一些成熟的算法。本文运用有限元程序分析泉州开元寺大雄宝殿和西塔，大雄宝殿的时程分析结果符合预期设想，西塔所建立的复杂模型和简单模型的模态分析结果两者存在一定的差异。但仍在可以接受的范围内。更多还原
