In order to protect Chinese ancient building, steel components were considered to strengthen its tenon-mortise joints and the strengthening effects were studied by shaking table tests.Based on actual sizes of an ancient building, a wooden frame model with a scale of 1 ∶ 8 of the prototype structure was built considering Yan-wei type of tenon-mortise connections.Steel components were used to strengthen tenon-mortise joints of the model to enhance its stability.By white noise excitation values of basic frequency for model in both strengthened and unstrengthened conditions were obtained; By inputing E1-Centro earthquake waves of different peak acceleration values, responses of displacement and acceleration for typical nodes of the model were obtained.Results show that after its tenon-mortise joints are strengthened by steel components, basic frequency of the model increases;Under earthquake the strengthened model responds with smaller peak displacement and acceleration values; With the increase of earthquake intensity, the steel components tend to perform better.Thus the steel components are effective for strengthening tenon-mortise joints of Chinese ancient buildings.
