Seismic Performance Evaluation of Traditional Wooden House by Alternate Cyclic Loading Test

摘要

It is important to establish the seismic design method and reinforcement method of traditional wooden buildings. To evaluate experimentally the seismic performance of a traditional wooden house built in 1898, static horizontal loading tests were carried out. The maximum bearing force was 106.6kN when the average deformation angle of wooden frame was about 1/10rad. Cracks in columns began occurring at column and tie-beam joints when the average deformation angle was about 1/25rad. After the bending fracture of all columns occurred, the wooden frame still kept the restoring force. The seismic performance of the house is also verified by an approximate response analysis. It is found that although the base shear coefficient, 0.18, is not enough because of the heavy roof, the house can be easily renovated by repairing deteriorated mud-walls and tie-beams.
