Unbonded beams on a two-parameter foundation

Unbonded beams supported by a foundation are studied. The foundation is assumed that tensile stresses cannot be transmitted across the interface between beams and their supporting subgrade. The subgrade is characterized by a two-parameter model proposed by Vlasov and Leont'ev, Pasternak and Fil...

Description
Summary:Unbonded beams supported by a foundation are studied. The foundation is assumed that tensile stresses cannot be transmitted across the interface between beams and their supporting subgrade. The subgrade is characterized by a two-parameter model proposed by Vlasov and Leont'ev, Pasternak and Filonenko-Borodich. Thus the shear strength of the foundation material is taken into account. With a suitable choice of parameters, analytical solutions are obtained and compared to experimental results reported by Durelli et al. The effects of the “lift up” of the beam and a discussion of the foundation parameters are also presented.
