Abstract: A detailed survey and inspection of the wood components was conducted during a structure renovation project at Yu Tomb of the Ming Dynasty. Visual classficication and nondestructive inspection procedures were employed to assess the physical and mechanical conditions of the wood members taken down from the Memorial Hall and the in-place members of the Three Gates and the Holy Beam. Stress wave timing and resistance micro-drilling tests were found effective in detecting internal structural defects of the wood components in ancient structures and providing scientific data for accurate condition classification. The results of this inspection project provided the architects and construction engineers reliable data to develop a cost-effective renovation plan that can maximize the reuse of the original materials, at the same time ensure the safety of the historic structure.
