Wood, as a biomaterial, could be easily deteriorated by microorganism and insects under a humid climate in Taiwan. However, the process of conserving these buildings mainly relies upon master carpenters to observe wooden components by visual inspection and knocking based on personal experiences at present. Due to their conservative attitude about conservation, the replacement of original wooden structural components is over highly. Furthermore, they cannot evaluate the actual mechanical properties of these components. In this study, nondestructive instruments will be used for investigation of the remnant mechanical properties of wooden structural members of historical building of Taipei - Fan Lan Building. The results could be as a very important restoration basis of Fan-Lan Building.古蹟建築木材損壞檢測木材剩餘強度Historical buildingsWood decay investigationRemnant mechanical properties of wood
