معرفی کتاب Experimental characterization of SDOF-embedded foundation systems with asymmetric interface condition

Various geometric and mechanical conditions for soil–foundation interfaces affect the superstructure and foundation
responses against earthquake. As one of these conditions, 2D asymmetry of soil around the embedded rigid foundation is
emphasized in the present paper. Accordingly, a reduced-scaled embedded foundation bearing SDOF superstructure is
considered under slow lateral cyclic and dynamic shake table tests in design and service levels at 1 g state, and the system
response is compared to those of systems containing surface and embedded foundations with symmetric condition. Test
results show the asymmetry in the moment–rotation response curve for system with asymmetric soil condition in static
state. While for dynamic response, the behavior under harmonic excitation with the design amplitude level is close to one
of system with surface foundation. In addition, the foundation moment capacity of nonlinear dynamic response can be
estimated properly through theoretical expression for foundation with asymmetric condition. Moreover, the rocking
behavior in two-way excitation causes significant loss of superstructure response relative to the foundation in all three
cases.
