The damages of reinforce concrete buildings on spread foundation could decrease with base slip behavior if the foundation base shear exceeds the friction strength at the base of the footings. Therefore, in this paper the static loading on the slip behavior was carried out to investigate the friction coefficients with various surface conditions which could be used at the base foundations. The tests show the average friction coefficients of 0.145, 0.121 and 0.108 for friction between steel-oil layer-steel plates, plastic-oil layer-plastic plates, and steel-oil layer-plastic plates, respectively.
