摘要

中国古建筑是华夏文明的重要组成部分，其精湛的结构技艺与独特的建筑美学对周边国家的古代建筑产生了深远影响。木结构建筑因其历史长和使用广范而成为中国最具特色的古建筑分支，随着时间的推移，该类建筑的保护日益迫切，了解和把握古建筑的结构动力特性能对其维修和保护具有重要意义。为在不损伤古建结构性能的条件下获得结构动力响应数据，利用自然环境激励对具有代表性的纯木古建筑飞云楼进行了动力测试。应用随机减量技术(RDT)对随机子空间识别 (SSI) 法的精度进行改进，利用改进的SSI对飞云楼的动力响应数据进行分析，获得了结构的自振频率，阻尼等模态参数，得到的飞云楼的动力特性参数能为保护该古建筑提供借鉴和依据。

Abstract

Chinese ancient architecture is a significant embranchment of Chinese civilization, whose exquisite construction technology and unique architectural aesthetic value has made profound influence on ancient buildings in surrounding countries. The protection of wooden architectures, the most Chinese style building because of its long civilized history and extensive distribution, is becoming more and more urgent accompanying the passing of time. Understanding and grasping the structural dynamic characteristics of the building has had great significance to its maintenance and protection. In order to collect dynamic response data under the condition of on damage to structural performance with tested ancient architecture, the pure wood structural building Feiyun pavilion which is a representative sample of Chinese ancient wood structure was carried on the dynamic test employing environment excitation. Modal parameters such as natural frequencies, damping solved by the Stochastic Subspace Identification (SSI) method combining the Random Decrement Technique (RDT) can offer references to protect this ancient building.
