Abstract
The friction characteristics of full-scale elastic sliding bearings were investigated from the results of dynamic tests performed under sinusoidal and seismic response loading. The dependence of friction coefficient on velocity, pressure and load repetition was clarified by sinusoidal loading tests. Based on the multiple regression analysis of test data, an expression for evaluating friction coefficients of elastic sliding bearings is suggested. From this, the time history of friction force that was observed in the seismic response loading tests was estimated. The simulated relationships between sliding displacement and shear force showed good agreement with the test results.
