摘要: Analytical equations for the moment– rotation response of a rigid foundation on Winkler soil model are presented. An equation is derived uplift-yield condition and combined with uplift- yield-only conditions to enable definition entire static response. The results obtained from developed show that inverse factor safety, x; has significant effect curve. value x ¼ 0:5 not only determines whether uplift or yield occurs first but also defines maximum footing. A based used analyze TRISEE experiments. computed agrees well experimental when subgrade modulus estimated using unload – reload stiffness plate load– deformation tests. comparison recommended NEHRP guidelines FEMA 273/274 documents shows choice effective shear significantly affected comparison. q 2003 Elsevier Science Ltd.
