碩士 === 淡江大學 === 土木工程研究所 === 83 === This paper computes the seismic bearing capacity factors of shallow foundations. The method adopted in this study was based on the Prandtl-Terzaghi''s failure mode and a perfect plastic Coulomb material. Rankine''s method for calculation of passive thrust was utilized in this study. The bearing capacity fctors NcE, NqE, and NrE of shallow foundations as well as bearing stress qult under seismic load were computated and tabulated. Defining a reduction ratio, ec(q,r), as the bearing capacity factors under seusmic load, Nc(q,r)E, and the same factors without the seismic load, Nc(q,r)S ;then, after analyses, ec and eq are very close to the same ratio extracting from the literature, while the er is somewhat smaller. This indicates the current method is conservative when compared with other solotions.
