宁波保国寺大殿残损分析及结构性能研究

Research on damage characteristic and structural performance of the main hall of Baoguo Temple in Ningbo

宁波保国寺大殿是江南最古老、保存最完整的木结构佛教建筑,目前损坏较为严重。为更好地保护和修缮该建筑,残损分析和结构性能研究是其修缮加固的科学基础。首先通过现场调研,对大殿的残损状况进行分析,找出其可见的病害;然后通过精确测绘及有限元模拟分析其结构性能,找出其隐在的病害;最后,综合残损分析及数值模拟结果,提出相应的修缮建议。

The main hall of Ningbo Baoguo Temple is the oldest and most integrated. Buddhism timber building in the south of the Yangtze River. But it has a serious damage now. In order to better preserve and repair the building, the research on structural performance and damage characteristic is necessary. This research is the scien- tific foundation of the repair. First, the damages of building were analyzed by the investigation on site. The visible problems were found out. Then the structural performance was researched by accurate survey and FEM analysis to research the potential problems. Finally, the repair suggestions of building were presented based on the results of damage investigation and theoretical analysis.
