Abstract: Several key in situ testing technology of inner defect and injury for ancient timber structures are put forward, such as establishment of working process,comparison optimum of non-destructive testing instruments, division of key testing area and general testing area, selection of non-destructive testing methods for members at the different position. And the non-destructive testing methods for timber columns non-wrapped and partly wrapped by stress wave and resistance instrument technology are put forward. The inner defect and injury of a certain temple′s ancient timber structure are tested on this basis. The results shows that the method is feasible and the data is scientific. It can accurately grasp inner defect and injury characteristics of ancient timber structures and provide reliable technology parameters and basis for subsequent safety appraisal and seismic appraisal.
Keywords: inner defect and injury; key testing area; non-destructive testing; stress wave; resistance instrument
