The rigidity of a structure reduces the differential settlement of soils through soil-structure interaction and at the same time it causes the additional stresses on the structure. In order to evaluate the responses due to differential settlements, it is necessary to make settlement analyses based on the soil-structure interaction. The Pasternak Model with two parameters is proposed for the soil-structure interaction analysis as an improved and refined model of the Winkler Model. Using the analytical model of an infinite Timoshenko Beam on the Pasternak Model, the responses of the beam due to differential settlements are analysed. The response functions are formulated in simple forms concerning displacements and stresses of the beam. The reduction effect of the soil itself on differential settlements is evaluated also. Furthermore, it is proved that the response functions can be applied to deterministic and stochastic analyses for differential settlements.
