To evaluate accurately the weight of traditional wood house, the weights of whole and principal members of typical traditional house so-called Kyo-machiya are examined. Here, the weights of two houses were measured. These houses are full-scale specimens for vibration tests carried out by using the E-defense shaking table in Miki-city. One was reconstructed at the test site by demolishing an old house, which was really built in 1932 in Kyoto-city. The other was newly constructed as a specimen. From the direct measurements of the whole houses, the real weight of old house is 353.14kN, and that of new house is 271.79kN. After the vibration tests, the houses were disassembled and the weights of principal members were also measured. The weights of houses obtained by the summation of each weight are about 5% less than the real weights. This difference is corresponding the weights of secondary members in houses. On the contrary, the weights calculation based on the Building Standard Law are about 15% heavier than the real weights.
