| 摘 要： | 为更好保护会善寺大雄宝殿，对会善寺大雄宝殿进行了现场调研，结合点云技术建立并验证其数值分析模型，研究了大雄宝殿的动力特性及在多遇地震作用下的动力响应。结果表明:结构基本自振周期为1.82s，体现石木结构长周期特性；在纵向多遇地震作用下，前檐木柱变形大于后檐石柱，结构除平动外还存在扭转；在横向多遇地震作用下，明间与次间木屋架有较大横向位移差，连接明间与次间木屋架的檩条和枋等纵向构件可能出现较大滑移并导致屋盖错位；在双向地震作用下，结构纵向和横向最大位移是单向地震作用下的1.1~1.2倍，扭转效应比单向地震作用下大。研究结果可为会善寺大雄宝殿及同类建筑的维修加固提供理论支持。

| Abstract: | To study the structural performance and provide guidances for the protection of the Chinese famous ancient buildings,the Great Buddha Hall of Huishan temple,a site survey of the Great Buddha Hall is conducted.The point cloud technology is adopted to build and verify the numerical analysis model.An effort is made to analyze the dynamic characteristics of the Great Buddha Hall and the dynamic responses when the structure suffered to the frequent earthquake actions.The results indicate that the fundamental natural period of vibration is 1.82 s.Under the longitudinal frequent earthquake action,the displacement of the brim pillar is more serious than that of the hind eave.Except translation responses,the structure also exists the torsion responses.Under the transversal frequent earthquake action,there are relative large displacement differences between the bright eave and second eave,and slides may occur for the purlin and balk which used to link the bright eave and second eave.With the effect of bidirectional earthquake action,the largest displacement differences of the structure is 1.1~1.2 times larger than those under the unidirectional earthquake actions.The effect of torsion is more obvious than that under the unidirectional earthquake actions.The study could be a basis for reinforcing the great buddha Hall of Huishan temple and a reference for repairing other ancient timber buildings. |
