Detection and analysis of the safety an ancient pagoda structure
In order to understand and grasp the existing defects and structural characteristics of ancient pagoda structure,this paper takes a stone ancient pagoda as an example,through the field investigation of damage and defects,adopts the horizontal observation method of con-necting pipe principle according to the unique shape and current situation of ancient pagoda to observe the settlement difference deformation of ancient pagoda,and adopts the measured natural vibration frequency of structural dynamic characteristics combined with the theoretical calculation frequency comparison of ancient pagoda.The results show that,The structure of the ancient tower has obvious damage,defects and deformation,and the structural stiffness has changed.At the same time,according to the experience of this method,it can be found that the measurement of connecting tube principle can be used for deformation observation under some unique shapes and limited conditions.The theoretical calculation frequency of building structure and the measured frequency of structural dynamic characteristics can be used to ana-lyze the stiffness of building structure at the present stage,and can also be used as a monitoring technique to judge whether the technical condition of building structure has deteriorated.
